In order to elucidate the effect of molecular structure of charge transfer complexes on the photoconductivity and electrical conductivity, charge transfer complexes were synthesized. Spectrophotometric measurement revealed a new absorption band to the complex of 2-methyl-imidazole (donor) and quinones (acceptor). The absorption maximum of complexes shifted to the longer wavelength than the acceptor used. The equilibrium constant and molar extinction coefficient was determined by using the Scott's equation. These values are quite low, respectively. The continuous method, infrared data and elementary analyses indicate the structure forming a 2: 1 complex with the acceptor sandwiched between two donor molecules. Electrical conductivity was found to be in the following order of electron acceptors;α-naphthoquinone>chloranil>bromanil>benzoquinone. Photoconductivity at 230 nm was enhanced in the following order of electron acceptors; benzoquinone≅bromanil>α-naphthoquinone>chloranil.
