Charge-transfer host system composed of 9,10-bis(3,5-dihydroxyphenyl)anthracene and methylviologen

By using 9,10-bis(3,5-dihydroxyphenyl)anthracene as an electron donor and 1,1′-dimethyl-4,4′-bipyri-dinium dichloride as an electron acceptor, a spontaneously resolved charge-transfer (CT) complex is formed. This CT complex can include n-alkyl alcohol molecules as guests, and the DRS of this CT complex change with the type of component guest molecules.
