Abstract
The relations among polyimide membrane colors, their gas transport and separation properties, and their fluorescence spectra were systematically investigated using fluorine-containing aromatic polyimide, 6FDA-TeMPD {[4,4-(hexafluoroisopropylidene) diphthalic anhydride] [(6FDA)-2,3,5,6- tetramethyl-1,4-phenylene-diamine (TeMPD)]}, which was used in electronic device and gas separation materials. Different molecular ordering structures of 6FDA-TeMPD polyimides were prepared by controlling kinds of casting solvents and dry conditions. This difference was based on the effect of charge transfer (CT) interaction formed by π electrons of ring structures in polyimide. Membrane color measured using s..
