Investigation of Low-Temperature Fluorescence and Absorption Spectra of Highly Stable Mero-Cyanines Derivatives of 2, 6-Di-Tert-Butyl-4-[R]-Cyclohexa-2, 5-Dienone
Abstract:This work presents the results of the investigation of the dependence of the fluorescence and absorption spectra of merocyanines, derivatives of the 2,6-di-tret-butyl-4-[R]-cyclohexa-2,5-dienone, on the nature of donor end groups (pyridinium, quinolinium, pyrilium, benzo[c,d]indolium, benzoimidindolium). Quantum-chemical calculation of the distribution was organized to electronic density and lengths of the relationships, which has shown that introduction tert-butyl groups in nucleus cyclohexa-2,5-dieno… Show more
