摘要：
We have successfully synthesized pi-conjugated microporous polymers (CMPs) via direct arylation of fluoroarenes with 2,4,6-tris(4-bromophenyl)-1,3,5-triazine. Both 1,2,4,5-tetrafluorobenzene and 1,3,5-trifluorobenzene were good monomers to give the networks, CMP1 and CMP2, respectively. Characterization of the insoluble materials was successfully achieved by high performance solid-state C-13 and F-19 CP/MAS NMR spectroscopy. The signals appeared in the aromatic region. No end group signals were observed in the C-13 NMR spectrum of CMP1, but CMP2 showed the unreacted C-H signal of the trifluorobenzene unit. CMP2 showed higher Brunauer-Emmett-Teller (BET) surface area than CMP1. The number of branch controlled (or tailored) the porosity of the polymer networks. The polymers have microporocity with CO2 capture capacity. The CO2 capture capacity of CMP2 (16.75 cm(3) g(-1)) was higher than that of CMP1 (11.49 cm(3) g(-1)) at 1.0 bar. (C) 2016 Elsevier Ltd.
