Phototropic Enzyme-dye Complexes

Abstract

THE term ‘phototropy’ has been applied to the phenomenon of a reversible change of colour induced by coloured lights, as in fulgides, and the change in or loss of colour of dye-stuffs in light of specific wave-length. The term has been used by chemists, botanists, biologists, and biochemists for many years to explain this phenomenon of change in colour of solids and solutions. Several reviews on the subject have been published1–6. A number of investigators have attempted to interpret the cause of phototropy in solutions7,8. The dyes most commonly used to explain the mechanism of this phenomenon have been the leucocyanides. The phototropy of malachite green leucocyanide has been investigated in dry alcohol and also in mixtures of alcohol and water by a number of authors9–15.
