POLYMERS FUNCTIONALIZED WITH BRØNSTED ACID GROUPS

摘要

Porous aromatic framework polymers functionalized with Brønsted acid moieites are prepared by polymerization of a three-dimensional organic aryl or heteroaryl monomer and its copolymerization with a second aryl or heteroaryl monomer functionalized with one or more Brønsted acid moiety. The polymers are characterized by a stable three-dimensional structure, which, in exemplary embodiments, includes interpenetrating subunits within one or more domain of the bulk polymer structure. The polymers are of use in methods of adsorbing ammonia and amines and in devices and systems configured for this purpose.

1. A porous aromatic polymer comprising a three-dimensional monomer according to Formula I: wherein
X is selected from C, Si, and a three-dimensional polycyclic cycloalkyl moiety;R1, R2, R3 and R4 are independently selected from H, substituted or unsubstituted alkyl (e.g., —CH2NR6R7, —CH2COOR6, —CH2S(O)2OR6, and —CH2P(O)(OR6)(OR7)), substituted or unsubstituted heteroalkyl, substituted or unsubstituted aryl, substituted or unsubstituted heteroaryl, halogen, CN, CF3, acyl, —SO2NR6R7, —NR6R7, —OR6, —S(O)2R6, —C(O)R6, —COOR6, —CONR6R7, —S(O)2OR6, —OC(O)R6, —C(O)NR6R7, —NR6C(O)R7, —NR6C(O)NR7R8, C(NR6)R7, —NR6SO2R7, —NO2, and —P(O)(OR6)(OR7), wherein two or more of R1, R2, R3, and R4, together with the atoms to which they are bonded, are optionally joined to form a ring system which is a member selected from substituted or unsubstituted cycloalkyl, substituted or unsubstituted heterocycloalkyl, substituted or unsubstituted aryl and substituted or unsubstituted heteroaryl, wherein
R6, R7, and R8 are members independently selected from H, substituted or unsubstituted alkyl, substituted or unsubstituted heteroalkyl, substituted or unsubstituted aryl, substituted or unsubstituted heteroaryl and substituted or unsubstituted heterocycloalkyl, and two or more of R6, R7, and R8, together with the atoms to which they are bonded, are optionally joined to form a 5- to 7-membered ring which is a member selected from substituted or unsubstituted cycloalkyl, substituted or unsubstituted heterocycloalkyl, substituted or unsubstituted aryl and substituted or unsubstituted heteroaryl; and the indeces a, b, c and d are members independently selected from the integers 0, 1, 2, 3, and 4, such that when a, b, c, or d is greater than 1, each R1, R2, R3 and R4, respectively, is independently selected.
