摘要：

The absorption and photoluminescence spectra of a number of derivatives of 3,3,6,6-tetramethyl-N-phenyl-decahydroacridine-1,8-dione with a regular change in the structure of molecules are investigated. Their electronic structure is calculated. The nature of some of the spectral bands is established. Significant differences in the efficiency of the processes of photochemical transformations of dyes exposed to UV irradiation have been revealed; these changes are attributable to the different donor-acceptor properties of the substituents introduced. A mechanism of phototransformations that agrees with both calculations of the electronic structure of molecules and the spectral-luminescent characteristics of the initial and irradiated compounds is suggested. © 2005 Springer Science+Business Media, Inc.
