A Review of Photochromism in Triphenylmethane Derivatives and Related Compounds

摘要

A comprehensive review of photochromism in triphenylmethane derivatives and some related compounds is presented. Most of the individual compounds reported to be photochromic as well as some of those reported as non-photochromic are mentioned. Compounds were included only if the conditions under which the observations were made were reasonably well described. In preparing the review little attention was given to the degree of photochromism reported since very little quantitative data are available. Physical properties of the compounds and/or their solutions which appear to be related to photochromism are discussed including conductivity, dielectric constant and dipole moment. Among other topics discussed are mechanisms and kinetic studies. (Author)
