Theoretical and Experimental Chemistry Aims and scope

Abstract

The reduction of electrical conductivity on illumination has been investigated in greater detail for a pyridine solution of safranine, and has also been observed for some dyestuffs of similar structure. It is suggested that the cause of the conductivity reduction is due to a diminution of the mobility of the cation of the dyestuff due to complex-formation between this and the molecules of the reducing agent due to the phototransfer of an electron. It has been shown experimentally that change in conditions may lead to a change in the sign of the effect, giving an increase in conductivity on illumination, which may be explained by the capacity of the molecule to undergo transition from reduction to oxidation under the changed conditions.
