Porous Molecular Solids

Purely Covalent Molecular Cages and Containers for Guest Encapsulation

“…Above a critical benzene-1,3,5-tricarboxaldehyde (23.13 mM) concentration, conversion decreases from 100% to 98%, and product isolation becomes more difficult . This synthetic strategy allows the synthesis of cages with different properties by the modification of building blocks to obtain self-assembled porous molecular materials for selective guest binding in either the crystalline or amorphous solid state …”

“…57 This synthetic strategy allows the synthesis of cages with different properties by the modification of building blocks to obtain self-assembled porous molecular materials for selective guest binding in either the crystalline or amorphous solid state. 58 Besides imine bond formation, other reversible reactions also allow to obtain cage structures. For example, alkyne metathesis is a reversible reaction that can be used to prepare cages, which generally provides thermodynamically stable products upon equilibrium.…”

Modeling Amorphous Microporous Polymers for CO2Capture and Separations

“…Numerous microporous materials have been explored to date for gas adsorption and separation, including both inorganic and organic, as well as crystalline and amorphous. A diagram illustrating some families of microporous materials is presented in Figure , many of which have been reviewed extensively in the literature. ,− Common examples of microporous materials are crystalline frameworks with well-defined pore structures, including zeolites, − zeolitic imidazolate frameworks (ZIFs), metal–organic frameworks (MOFs), ,− and covalent organic frameworks (COFs) . Amorphous networks with ill-defined pore structures, like activated carbons and carbon molecular sieves (CMSs), have also been explored.…”
