In order to prepare good thin films based on organic donor molecules, three new alkyl-substituted BEDT-TTF (ET) molecules and its analogs, C 6ET 1, BC 6ET 2 and C 6EDT-DC 3 are synthesized. Solubilities of the present materials are much improved from ET. C 6ET and BC 6ET have almost the same donor ability as that of ET. These three materials form good thin films on a SiO 2 substrate by the solution cast method. Key words. Synthesis, thin films, organic conductors.
