3,3 0 -Di(9-(4-butylphenyl)carbazyl) and 3,3 0 -di(9-ethylcarbazyl)-based hydrazones were synthesized by the multi-step synthetic route including oxidative dimerization of 9-(4-butylphenyl)carbazole and 9-ethylcarbazole, formylation of the dimmers obtained and the reactions of the formyl derivatives with different hydrazines. The chemical structure of the compounds was confirmed by 1 HNMR, IR and mass spectroscopy. The hydrazones synthesized form stable glasses with the glass transition temperatures exceeding 140 C. The values of ionisation potentials measured by electron photoemission technique are in the range of 5,21-5,4 eV. The hole drift mobilities in the films of the 50% solid solutions of the hydrazones in Financial support from Samsung Electronics and from the Lithuanian State Science and Studies foundation is gratefully acknowledged. 95=[407]bisphenol Z polycarbonate established by the xerographic time-of-flight technique exceed 10 À5 cm 2 =Vs at high electric fields.

This research was supported by NSF energy changes for reactions 3, 5, and 9, this is certainly the case. While not necessarily anticipated by them, these results are comDatible with our earlier findines from electrochemical Grants CHE 80-06601 and CHE 81-06017,
