Abstract
A one-pot polycondensation of 4,4'-(hexafluoroisopropylidene)bis(benzo acid) 1 with terephthalic dihydrazide 2 and/or hydrazine sulfate 3 affords aromatic oxadiazole polymers 4, 5 and 6, respectively, the optical and electrochemical properties of which have been investigated for applications as charge transporting layers in electroluminescent devices.
