Recently, the 2025 Nobel Prize in Chemistry was awarded to Susumu Kitagawa, Richard Robson, and Omar Yaghi in recognition of “their development of metal–organic frameworks (MOFs).”

The three laureates created molecular structures with enormous internal spaces, allowing gases and other chemical species to flow through them. These structures, known as Metal–Organic Frameworks (MOFs), have applications ranging from extracting water from desert air and capturing carbon dioxide, to storing toxic gases and catalyzing chemical reactions.

Metal–Organic Frameworks (MOFs) are a class of crystalline porous materials formed by metal ions or clusters linked via organic ligands (Figure 1). Their structures can be envisioned as a three-dimensional network of “metal nodes + organic linkers,” combining the stability of inorganic materials with the design flexibility of organic chemistry. This versatile construction allows MOFs to be composed of almost any metal from the periodic table and a wide variety of ligands, such as carboxylates, imidazolates, or phosphonates, enabling precise control over pore size, polarity, and chemical environment.

 

Figure 1. Schematic of a Metal–Organic FrameworkFigure 1. Schematic of a Metal–Organic Framework

 

Since the first permanent-porosity MOFs appeared in the 1990s, thousands of structural frameworks have been developed, including classic examples like HKUST-1 and MIL-101. They exhibit ultrahigh specific surface areas and pore volumes, offering unique properties for gas adsorption, hydrogen storage, separation, catalysis, and even drug delivery. Some flexible MOFs can undergo reversible structural changes in response to adsorption or temperature, showing dynamic behaviors such as “breathing effects.” Thanks to their diversity, tunability, and functionalization, MOFs have become a core topic in porous materials research and provide a solid scientific foundation for studying adsorption performance and characterization methods.

 

MOFs Characterization

The fundamental characterization of MOFs typically includes powder X-ray diffraction (PXRD) patterns to determine crystallinity and phase purity, and nitrogen (N₂) adsorption/desorption isotherms to validate the pore structure and calculate apparent surface area.

Other commonly used complementary techniques include:

  • Thermogravimetric Analysis (TGA): Evaluates thermal stability and can estimate pore volume in some cases.

  • Water Stability Tests: Assesses structural stability in water and across different pH conditions.

  • Scanning Electron Microscopy (SEM): Measures crystal size and morphology, and can be combined with energy-dispersive X-ray spectroscopy (EDS) for elemental composition and distribution.

  • Nuclear Magnetic Resonance (NMR) Spectroscopy: Analyzes overall sample purity and can quantify ligand ratios in mixed-ligand MOFs.

  • Inductively Coupled Plasma Optical Emission Spectroscopy (ICP-OES): Determines sample purity and elemental ratios.

  • Diffuse Reflectance Infrared Fourier Transform Spectroscopy (DRIFTS): Confirms the presence or absence of IR-active functional groups in the framework.

  • Single-Crystal X-ray Diffraction (SCXRD): Provides precise structural information.

Below is a brief overview of sample preparation and key data analysis points for each characterization method.

 

1. Powder X-ray Diffraction (PXRD)

PXRD determines the crystal structure and phase purity. Experimental diffraction patterns are compared with simulated patterns from single-crystal XRD data to confirm phase purity. Samples are typically measured as powders pressed into pellets or loaded into capillaries, with rotation applied during measurement to avoid preferred orientation effects. Peak broadening usually indicates small crystallite size rather than poor crystallinity.

 

2. Nitrogen Adsorption/Desorption Isotherms

N₂ adsorption/desorption isotherms, measured at 77 K, are used to confirm pore structure, calculate surface area and pore volume, and evaluate pore size distribution. To ensure reliable measurements, samples must be fully activated to remove solvents, and sample mass is critical — the product of sample mass (g) and specific surface area (m²/g) should typically exceed 100 m².

Surface area is calculated using the BET model. Accurate BET results depend on proper selection of the linear region of the isotherm following Rouquerol criteria. Incorrect selection can lead to several-fold deviations in surface area (Figure 2, Table 1). CIQTEK Climber series instruments feature automated BET point selection, eliminating human error and providing reliable results even for MOFs.

3. Thermogravimetric Analysis (TGA)

TGA evaluates thermal stability and can roughly estimate pore volume based on solvent loss. The decomposition behavior depends strongly on the carrier gas (N₂, air, O₂), which should be noted in reports. Combining TGA with variable-temperature PXRD or adsorption experiments can verify structural stability after thermal treatment.

 

4. Scanning Electron Microscopy (SEM)

SEM observes crystal morphology and size, and can be combined with EDS for elemental analysis. Since MOFs are often insulating, charging artifacts can occur, usually mitigated by coating with a conductive layer (e.g., Au or Os). Accelerating voltage affects resolution and surface details: higher voltages yield clearer crystal outlines but may damage surface features. For EDS quantification, coating elements should be considered to avoid overlapping signals with target metals.

5. Other Complementary Techniques

  • ICP-OES/MS: Quantifies metal ratios and detects impurities or leaching; samples must be fully dissolved via acid digestion.

  • NMR Spectroscopy: Dissolution NMR measures ligand ratios, residual modulators, and solvent removal; solid-state NMR probes ligand environments and molecular interactions.

  • DRIFTS: Confirms characteristic functional groups in the framework and studies adsorption under gas flow or variable temperatures.

 

Combining multiple characterization methods provides a comprehensive view of MOFs’ structure, porosity, and composition, offering reliable support for performance analysis and mechanistic studies.

In the rapidly advancing world of wireless communication, radar systems, and high-speed digital applications, the performance of your printed circuit board (PCB) is non-negotiable. At the heart of every high-frequency system lies the PCB substrate, a material that fundamentally determines signal integrity, loss, and overall reliability. For engineers pushing the boundaries of technology, standard FR-4 materials fall short. This is where Wangling TF PCBs, engineered with specialized ceramic-filled PTFE composites, emerge as the superior solution. But what specific attributes make them the ideal choice for your most demanding projects?

 

Advanced Material Composition: The Foundation of Performance

 

Wangling TF laminates are not your ordinary PCB materials. They represent a sophisticated composite engineered for excellence. The core structure is based on a unique formulation of polytetrafluoroethylene (PTFE) resin, renowned for its exceptional microwave properties, combined with a precisely measured ceramic filler. A key differentiator is the deliberate absence of fiberglass cloth, which can introduce inconsistencies in the dielectric constant (Dk). By eliminating this variable and fine-tuning the ratio of ceramic to PTFE, we achieve unparalleled control over the dielectric constant. This meticulous material science, coupled with specialized production processes, results in a laminate that delivers outstanding dielectric performance and a high degree of long-term reliability, essential for mission-critical applications.

The superiority of TF High-Frequency PCBs is quantified through a set of exceptional characteristics:


TF PCB's features

 

1) Precise and Stable Dielectric Constant (Dk): TF laminates offer a stable and broad range of dielectric constants, spanning from 3.0 to 16.0. Common values such as 3.0, 6.0, 9.2, 9.6, 10.2, and 16 are readily available. This stability across frequencies is critical for maintaining consistent impedance control and preventing signal distortion in high-speed designs.

 

2) Exceptionally Low Loss Tangent (Df): Signal loss is a primary concern in high-frequency circuits. TF laminates excel with an ultra-low dissipation factor (Df), a measure of signal energy lost as heat. For instance, for Dk values between 3.0 and 9.5 at 10GHz, the loss tangent is an impressively low 0.0010. This minimal loss ensures stronger signals, greater range, and improved overall system efficiency.

 

3) Exceptional Thermal Stability and Range: Performance cannot falter under thermal stress. TF materials surpass standard high-temperature options with an extensive operational temperature range of -80°C to +200°C. This ensures reliable performance in harsh environments, from aerospace applications to high-power equipment, without degradation of electrical properties.

 

4) Versatile Physical Properties: To accommodate diverse design requirements, these laminates are available in thicknesses from 0.635mm to 2.5mm.

How Can TP High-Frequency PCBs with Customizable Dk Enhance Your High-Speed Designs?


Introduction


In the competitive landscape of high-frequency electronics, the choice of printed circuit board (PCB) substrate is a critical determinant of performance. Wangling TP High Frequency PCB material stands out as a uniquely innovative solution within the industry. This specialized substrate is a high-frequency thermoplastic composite where the dielectric layer is engineered from a precise blend of ceramic particles and Polyphenylene Oxide (PPO) resin, notably formulated without traditional fiberglass reinforcement. This distinct composition allows for unparalleled control, as the dielectric constant (Dk) can be meticulously fine-tuned by altering the ratio between the ceramic filler and the PPO resin. The sophisticated manufacturing process behind TP PCB laminates yields a material that exhibits not only superior dielectric properties but also exceptional reliability, making it a premier choice for advanced applications where signal integrity is non-negotiable.

Exceptional Material Features and Properties


TP PCB Material Features and Properties


The defining characteristic of TP PCB material is its tunable dielectric constant. Engineers can specify a Dk value within a broad spectrum of 3 to 25 to precisely match their circuit's impedance requirements. This stability across the board ensures consistent performance, with commonly utilized values including 3.0, 4.4, 6.0, 6.15, 9.2, 9.6, 10.2, 11, 16, and 20.


Signal loss is a primary concern in high-frequency designs, and TP material addresses this with a very low dielectric loss (Df). While all materials experience some increase in loss at higher frequencies, the TP formulation demonstrates remarkable stability, with only a minimal rise within the popular 10 GHz operational range, thereby preserving signal strength and quality.


Operational endurance is another key strength.TP High Frequency PCBs are built to perform reliably across an extensive temperature range from -100°C to +150°C, showcasing outstanding resistance to thermal stress, particularly in low-temperature environments. It is crucial for designers to note that exposure to temperatures exceeding 180°C should be avoided, as this can lead to mechanical deformation, potential delamination of the copper foil, and significant alterations to the electrical characteristics.


Further enhancing its suitability for demanding environments, the material possesses inherent radiation resistance and exhibits low outgassing properties, a vital characteristic for applications in vacuum or aerospace settings. Compared to vacuum-deposited ceramic substrates, TP laminates offer a more robust and reliable bond between the copper foil and the dielectric core, significantly reducing the risk of copper peel-off and ensuring long-term structural integrity.
