Abstract

Isolated successes of coordination copolymerization for the production of microporous coordination polymers (MCPs) have been reported recently; the logic for this synthetic approach has not been established nor have the key features of the synthetic conditions needed to generalize the method. Here, we establish guidelines for application of the copolymerization technique by exploring coordination modes and report, in addition to details on two previous coordination copolymers with exceptional properties, three new MCPs: UMCM-3 (Zn4O(2,5-thiophenedicaboxylate)1.2(1 ,3,5-tris(4- carboxyphenyl)benzene)1.2) UMCM-4 (Zn40(1,4-benzenedicarboxylate)3/2(4,4′,4″-tricarboxytriphenyl-amine)), and UMCM-5 (Zn4O(1,4-naphthalenedicarboxylate)(1,3,5-tris(4-carboxyphenyl)benzene)4/3). The MCPs prepared by the copolymerization technique demonstrate Brunauer-Emmett-Teller (BET) surface areas between 3500-5200 m2/g and high pore volumes (1 .64-2.37 cm3/g). In addition, the alignment of poly(3-hexylthiophene) within mesoporous channels of UMCM-1 is reported as a demonstration of the unique properties of these hosts. [ABSTRACT FROM AUTHOR]
