Synthesis and properties of the well-defined 3,6-dibromocarbazolyl-containing molecular glasses are reported. They were prepared by the nucleophilic opening of the oxirane ring of 1,3-di(3,6-dibromocarbazol-9-yl)-2-propanol glycidyl ether with aniline, 4-fluoro-, 4-bromoanilines, 2,5-dimercapto-1,3,4-thiadiazole or glycidyl ether of 1,3-di(carbazol-9-yl)-2-propanol with 4,4'-thiobisbenzenethiol and 1,9-nonanedithiol followed by bromination. The obtained materials were examined by various techniques including differential scanning calorimetry, NMR, MS, UV, PL spectrometry. The electrophotographic parameters of the molecular glasses doped with difluoroboron-1,3-bis(4-metoxyphenyl)-1,3-propanedionate have been studied. The electrochemical properties and ionization potentials, measured by electron photoemission method in air, were investigated. (C) 2011 Elsevier B.V. All rights reserved.
