摘要：

Efficient syntheses are described for five new vinylogous pi-electron donors, viz. 5, 6, and 8-10, which are related to bis(ethylenediseleno)tetrathiafulvalene (3): symmetrical and unsymmetrical systems, containing mixed alkylseleno and alkylthio groups, have been obtained. The solution electrochemical redox properties, studied by cyclic voltammetry, establish that these molecules undergo two, single-electron, oxidations at low potentials. The single-crystal X-ray structure of 4,5-bis(methylseleno)-4',5'-bis(methylthio)-2,2'-ethanediylidene(1,3-dithiole) (6) is reported. Semiconducting complexes of the new donors with tetracyano-p-quinodimethane have been obtained.
