Cooperative proton-electron transfer in a supramolecular structure of meso-1,2-bis[4-(dimethylamino)phenyl]-1,2-ethanediol and bis(4-cyanobenzylidene)ethylenediamine.
A supramol. 1:1 complex of the title compds. was prepd. and its elec., optic, and magnetic properties were studied. It undergoes light-induced cooperative proton-electron transfer which is switched back by heating to 60 Deg. The complex exhibits a unique form of photochromism and displays paramagnetism.
