NOVEL ELECTRON-DONATIVE COMPOUND AND ELECTRICALLY CONDUCTIVE CHARGE TRANSFER COMPLEX USING THE SAME

摘要

NEW MATERIAL:The compound of formula I (R1 and R2 are lower alkyl, CH3-S or R1 and R2 together form S-CH2-S or S-CH2CH2-S to form a ring; X and Y are S or Se). EXAMPLE:4,5-Dimethyl-1,3-dithiol-selone. USE:An electron-donative compound. It is combined with various electron acceptors to form an electrically conductive charge-transfer complex. PREPARATION:A compound of formula II and a compound of formula III are heated in a solvent in the presence of a trialkyl phosphite, etc., and the obtained compound of formula IV is heated in a solvent in the presence of a quinoid compound (e.g. chloranil).
