  Red and Near-Infrared Photoluminescence of D-π-A-Type Compounds Based on a 1,4-Diaryl-1-thio-1,3-butadiene Conjugated System in a Dibenzobarrelene Skeleton

  摘要：

  1,4-Diaryl-1-thio-1,3-butadiene derivatives having a pi-donor dimethylamino group and several pi-acceptor substituents at both terminals of the conjugated system were synthesized by intramolecular [4 + 2] cycloaddition of 1-thio-enynes and subsequent chemical transformations. They displayed largely red-shifted absorption and emission spectra in solution, the powder state, and in polymer films. The derivatives with a 2,2-dicyanoethenyl group as the p-acceptor exhibited inverted solvatochromism in both optical absorption and fluorescence spectroscopies.
