Synthesis and absorption/emission spectral properties of styrylstilbene and distyrylanthracene derivatives

Abstract

A series of para-substituted styrylstilbenes I and 9,10-distyrylanthracenes II was synthesized by Wittig or Arbusov–Horner reaction as a key step. Subsequently, systematic investigations were carried out on their absorption and fluorescence spectra, and their chemiluminescence properties. It has become apparent that substituent effects are present in each π-electron system. Pariser–Parr–Pople self-consistent field configurational interaction molecular orbital (PPP-SCF-Cl-MO) calculations on some representatives of each series I and II were put into practice by considering the geometry of excited states, and the values obtained were well correlated with the experimental results.
