Abstract
Synthesis, thermal, optical and photoelectrical properties of N,N-diarylated indolo[3,2-b]carbazole derivatives, bearing six strategically placed alkoxy chains of different length, are reported. Electron photoemission spectra of the synthesized derivatives have been recorded and the ionization potentials have been established. It was found that the best charge transport properties were shown by 5,11-di(1,2,3-trioctadecyloxyphenyl)indolo[3,2-b]carbazole. Room temperature hole-drift mobility in its 50% solid solution in bisphenol Z polycarbonate established by the xerographic time of flight technique was found to exceed 10−6 cm2 V−1 s−1 at an electric field of 106 V cm−1.
