Book Description
In a previous paper, the photobleaching and dark-regeneration of complexes containing sulphydryl compounds and a fluorescent dye were reported. Proteins were included in the sulphydryl compounds investiggated. The dye is a derivative of 3',6'-dichlorofluoran. It was proposed that photobleaching is due to an electron transfer within the complex from the sulphur to the excited conjugated dye molecule. A triplet state was considered to play some part in this electron transfer. This article presents experimental evidence confirming triplet formation and an electron transfer mechanism. Triplet formation of the dye is shown to be enhanced when complexed to the sulphur of a protein. The protein-dye complex shows greater photsensitivity than the simple dye -S-H complex. The phenomenon reported in this paper may shed light on the function of sulphydryl groups in proteins containinggvisual pigments and the phycobilin pigments which are present in photosynthetic organisms.

Book Description
Mercaptoethanol and dimercaptopropanol form a complex with a cationic dye. Two dyes interacting with two SH groups in the complex with dimercaptopropanol exhibit two different absorptions and two different phosphorescences. Each one of them, present at a shorter wave length, corresponds to an absorption and a phosphorescence of the complex with mercaptoethanol. The dye-dimercaptopropanol complex is more photosensitive than the dye-mercaptoethanol complex. A phototropism observed in the former complex is based on an electron transfer.
