Synthesis, characterization and photophysics of polyplatinaynes based on bis(9,9-dibutyl-2,7-fluorenyl)-2,1,3-benzothiadiazole derivatives

2,1,3-Benzothiadiazole (BT) and its derivatives are very important acceptor units used in the development of photofunctional compounds and are applicable for the molecular construction of organic optoelectronic devices. Due to their strong electron-withdrawing ability, construction of molecules with the unit core of BT and its derivatives can usually improve the electronic properties of the resulting organic materials. New organometallic acetylide polymers of platinum(II) bridged by bis(fluorenyl)-benzothiadiazole moiety P1 and P2 have been synthesized via the CuI-catalyzed dehydrohalogenation reaction of the platinum(II) chloride precursors and the corresponding diacetylene ligands. The photophysical, thermal and electrochemical properties of P1 and P2 were investigated.
