Porous materials
11717803 · 2023-08-08 ·

Porous materials (such as organic polyamine cage compounds) and methods of stabilising porous materials which are otherwise prone to pore-collapse are described. Such stabilisation is accomplished through the use of molecular ties to create bridges between reactive groups of a (potentially) porous material to thereby strengthen and stabilise the porous structure. The chemistry involved in, and the results of, the stabilisation of porous materials to provide a new sorption composition comprising the very materials which are generally prone to pore-collapse are also described.
