SYNTHESIS AND STUDY OF FLUORESCENT PROPERTIES OF BENZOTHIAZOLYLTHIENOTHIOPHENE DERIVATIVES

Abstract

A number of benzothiazolylthienothiophenes have been synthesized. Spectral studies have revealed that all these compounds have fluorescent properties that depend on their structure. Dependence of absorption and fluorescence bands positions on the nature of substituents have been established. Increase of the electron-withdrawing nature of substituents led to bathochromic shift of the absorption and fluorescence bands as well as to decrease of the fluorescence intensity.
