Two major categories of organic solids are known to offer the prospect of electrical conduction. One of them consists of charge‐transfer complexes such as BEDT‐TTF salts. A large number of studies on charge‐transfer complexes have been carried out and their conductivity ranges from semiconductor to superconductor. The other group comprises single component materials. Typical examples are polycyclic aromatic compounds and also phthalocyanines; their conductivities are not as good as those of the donor‐acceptor kinds. 1) As one of those single component organic semiconductors, a group of cytochromes, electron carrier in biological system, was offered. Cytochrome c 3 (molecular weight = 13,995, 107 amino acid residers), an electron carrier in the reactions of very negative potentials in cells of Desulfovibrio, has four homes in the molecule.
