We present a procedure for highly controlled and wrinkle-free transfer of block copolymer thin films onto porous support substrates using a 3D-printed drain chamber. The drain chamber design is of general relevance to all procedures involving transfer of macromolecular films onto porous substrates, which is normally done by hand in an irreproducible fashion.

For transition metal complexes, the coordination number determines the geometry around the central metal ion. Table 1 compares coordination numbers to molecular geometry. The most common structures of the complexes in coordination compounds are octahedral, tetrahedral, and square planar. Coordination Number Molecular Geometry Example 2 linear [Ag(NH3)2]+ 3 trigonal planar [Cu(CN)3]2− 4 tetrahedral(d0 or d10), low oxidation...

The word polymer is derived from the Greek words “poly” which means “many” and “mer” which means “parts”. Polymers are long chains of molecules composed of repeating units of smaller molecules, known as monomers. They either occur naturally, such as DNA and proteins, or can be constructed synthetically, like plastics. They have varied structural characteristics, such as linear chains, branched chains, or complex networks, that contribute to the properties that they exhibit. Additionally,...

In most main group element compounds, the valence electrons of the isolated atoms combine to form chemical bonds that satisfy the octet rule. For instance, the four valence electrons of carbon overlap with electrons from four hydrogen atoms to form CH4. The one valence electron leaves sodium and adds to the seven valence electrons of chlorine to form the ionic formula unit NaCl (Figure 1a). Transition metals do not normally bond in this fashion. They primarily form coordinate covalent bonds, a...
FAQs
Metal ions or clusters establish coordination points, while multitopic organic ligands connect those points into an extended framework. Changing either component can alter pore size, pore shape, and the chemical functionality of internal surfaces. This modularity lets chemists adjust molecular access and interactions, linking structural design directly to capture, separation, storage, or catalytic performance.
Molecules can enter the permanent pores and interact with internal surfaces through coordination chemistry, electrostatic forces, or adsorption. The strength and character of these interactions influence which molecules are retained, how they diffuse, and whether reactants become concentrated near one another. Consequently, pore chemistry helps determine selective capture and separation behavior.
These three features govern both molecular access and the environment experienced inside a framework. Pore dimensions influence which molecules can enter and move through the network, while surface functionality affects how they interact with the material. Together, they can promote selective uptake, control diffusion, or create confined environments that support chemical reactions.
A rational design approach varies the metal node, the organic ligand, and the synthesis conditions rather than treating the framework as fixed. These choices provide ways to adjust stability alongside pore structure and chemical function. The resulting material can then be matched to a targeted role, such as gas purification, sensing, storage, catalysis, or remediation.
They are useful when a material must selectively capture gases or separate a molecular mixture. Their permanent pores provide internal space for molecules to enter, while pore dimensions and surface chemistry influence diffusion and interactions. By changing framework components, researchers can design materials aimed at particular purification or separation requirements rather than relying on a single universal structure.
The same tunable pore environments support several chemistry applications. PCPs can store chemicals, concentrate reactants for catalysis, and provide functional surfaces for sensing. Their potential also extends to energy storage and environmental remediation. In each case, researchers exploit the relationship between framework composition, internal accessibility, and molecular interactions to obtain a desired chemical function.
