Abstract

Films of nanosized composites of poly(N-epoxypropylcarbazole) (pEPC) and poly(3,6-di-Br-N-epoxypropylcarbazole) (pdBEPC) with vanadium pentoxide (V2O5) are produced for the first time ever. The electroconduction in dark and when illuminated, absorption spectra, steady-state photoluminescence spectra, and time-resolved photoluminescence spectra for the composite films are studied. The results are compared with relevant data for the pEPC, pdBEPC, and V2O5films. A conclusion about the formation of donor–acceptor complexes with incomplete charge transfer [pEPC+σ···V2O -σ5 ] and [pdBEPC+σ···V2O5 -σ] is made. The surface morphology of the composites differs in the size of V2O5 fibers and polymer grains; the polymer inclusions in the composites are of different character. A surface morphology study reveals that the composite constituents—polymer base and V2O5 fibers—are nanosized.
