Paper Abstract

The dyperchlorates of N,N'-dy(2-dygydroxyethyl)-4,4'- dipyridylium (IX) and of N,N'-dy(carbethoxymethyl)-4,4'- dipyridylium (X)(such named viologenes) are the perspective dye-dopants to work out the new photorefractive materials. The X-ray investigation of single crystals of IX and X was carried out. It has been shown that in the charge transfer absence the flat structure of dipiridilium core at IX, X are determined by electronic effects of hydroxyl and ether groups which contain non-separated electronic pairs. Such structure flatness is favor for effective cation-radicals formation.
