Xc. Li et al., SYNTHESIS AND OPTOELECTRONIC PROPERTIES OF AROMATIC OXADIAZOLE POLYMERS, Journal of the Chemical Society, Chemical Communications, (21), 1995, pp. 2211-2212
A one-pot polycondensation of 4,4'-(hexafluoroisopropylidene)bis(benzo
acid) 1 with terephthalic dihydrazide 2 and/or hydrazine sulfate 3 af
fords aromatic oxadiazole polymers 4, 5 and 6, respectively, the optic
al and electrochemical properties of which have been investigated for
applications as charge transporting layers in electroluminescent devic
es.
