Abstract: Carbazole-based molecular photoconductive charge-transfer complexes are synthesized which are easily applied to electrode substrates. The carbazole-based complexes comprise 3-substituted carbazoles complexed with an electron acceptor molecule such as 2,4,7-trinitrofluorenone. In addition, the photoconductive response of polyvinylcarbazole-trinitrofluorenone complexes is improved by substitution of certain functional groups on the aromatic portions of the polymer. Also provided are methods for constructing photoconductive elements on thin semitransparent flexible substrates for use in many areas such as light sensitive switching functions, the photoconductors being applied from solution or suspension in a fast drying liquid onto an electrode assembly attached to a flexible plastic substrate.
