Pristine and Carboxyl-Functionalized Tetraphenylethylene-Based Ladder Networks for Gas Separation and Volatile Organic Vapor Adsorption.

ABSTRACT: A novel tetraphenylethylene-based ladder network (MP1) made by polycondensation reaction from 4,4',4″,4‴-(ethene-1,1,2,2-tetrayl)tetrakis(benzene-1,2-diol) and 2,3,5,6-tetrafluoroterephthalonitrile and its COOH-functionalized analogue (MP2) were synthesized for the first time. Their structures were confirmed by solid-state nuclear magnetic resonance (¹³C cross-polarization magic angle spinning), Fourier transform infrared spectroscopy, and elementary analysis. MP1 exhibited a high Brunauer-Emmett-Teller surface area (1020 m² g^-1), whereas the COOH-functionalized MP2 showed a much smaller surface area (150 m² g^-1) but displayed a more uniform pore size distribution. Because of the high density of nitrile groups in the network polymers o
