NEW MATERIAL:Naphthaceno[1,12-cd:4,5-c'd']bis[1,2]diselenol of formula I, 1,4,5,12-tetrachloronaphthacene of formula II, 1,4,5,5,12,12-hexachloro-5,12- dihydronaphthacene of formula III and 2,3-dihydro-5,12-dihydroxy-1,4- naphthacenequinone of formula IV.
EXAMPLE: An electron donor constituting a charge transfer complex having high electrical conductivity.
USE: The compound of formula IV can be produced by treating 1,4-dihydroxy-5,12- naphthacenequinone of formula V with an alkali metal carbonate and Na hydrosulfite, etc., in a water-soluble organic solvent (e.g. acetone) in the presence of water. The obtained compound of formula IV can be converted to the compound of formula III by treating with PCl5 in an organic solvent. The compound of formula II is produced from the compound of formula III by treating with SnCl2 in acetic acid solvent in the presence of concentrated hydrochloric acid. The compound of formula I is produced by treating the compound of formula II with Na and Se in DMF.
