ABSTRACT:
Photoconductive materials are prepared from a dicarbazolyl compound and a Lewis acid. The materials are charge transfer complexes, with the dicarbazolyl compound, such as 1, 2-dicarbazolyl cyclobutane acting as an electron donor and the Lewis acid, such as 2, 4, 7-trinitro-9-fluorenone acting as an electron acceptor. The molar ratio of the donor to the acceptor can be in the range from 1:0.5 to 1:5.
