Synthesis and optoelectronic properties of a novel molecular semiconductor of dithieno[5,6-b:11,12-b′]coronene-2,3,8,9-tetracarboxylic tetraester

A facile procedure for the synthesis of dithieno[5,6-b:11,12-b′]coronene-2,3,8,9-tetracarboxylic tetra(2-ethylhexyl)ester (DTCTTE-EH) from readily available perylene-3,4,9,10-tetracaroboxylic dianhydride is described. The electronic properties of DTCTTE-EH were elucidated on the basis of UV–vis spectra, emission spectrum and electrochemical measurement, which demonstrate that DTCTTE is a new class of components for promising semiconducting materials.

Dithieno[5,6-b:11,12-b′]coronene-2,3,8,9-tetracarboxylic tetraester (DTCTTE), a novel class of semiconducting polycyclic aromatic molecules, was synthesized and characterized.Figure optionsDownload as PowerPoint slide
