摘要

The synthesis of a poly (1, 3-dithienylisothianaphthene)(PDTITN) derivative obtained via oxidative polymerization of 5, 6-dichloro-1, 2-bis (3'-dodecylthienyl) isothianaphthene is described. PDTITN exhibits a band gap of 1.80-1.85 eV. The redox properties of PDTITN were characterized using cyclic voltammetry and spectroelectrochemisty. Photoexcitation of PDTITN results in photoluminescence (PL) in the near-IR region and the formation of a ...
