A Novel Low-Bandgap Conjugated Polymer Based on Ru( II) Bis( acetylide) Complex and BODIPY Moieties
A novel conjugated polymer P-1 incorporating Ru(II) bis(acetylide) complex and borondipyrromethene (BODIPY) moieties in the main chain was synthesized by Pd-catalyzed Sonogashira coupling reaction of diethynyl substituted BODIPY derivative (M-1) and Ru(II) bis(acetylide) complex (M-2), and the reference polymer P-2 was obtained from the same method as preparation of P-1. Compared with P-2, Ru(II)-containing polymer P-1 shows low-bandgap as 0.87 eV from cyclic voltammetry, and obvious redshifts in both UV-vis absorption and fluorescence spectra.
