Abstract

Two new solution-processible platinum(II) polyyne polymers P1 and P2 bridged by diketopyrrolopyrrole and isoindigo units have been synthesized via the CuI-catalyzed dehydrohalogenation reaction of the platinum(II) chloride precursors and the corresponding diacetylene ligands. The photophysical and electrochemical properties of P1 and P2 were investigated. These metallo-organic polymers have relatively narrow bandgaps of around 1.58–1.70 eV and broad absorption bands which are favorable for harvesting solar energy.
