A novel pi-conjugated polymer (PCQH) containing N-benzylcarbazole and 8-methoxyquinoline units has been successfully synthesized and characterized. The polymer possesses good thermal stability with the decomposition temperature (Td) of 295 degrees C and the glass transition temperature (Tg) of 250 degrees C. The absorption and emission spectra show that the polymer can emit blue light with higher fluorescence quantum yield (81%) in CHCl3. With the increase of solvent polarity, the emission peaks of PCQH display an obvious red-shifted. The study of the interactions of PCQH with electron donor (DMA) and electron acceptor (DMTP) indicates that the polymer has excellent electron transfer property. Furthermore, the interactions of PCQH with carbon materials (C-60 and CNTs) also have been investigated. The electrochemical properties and energy levels of PCQH were calculated by the Gaussian 09 software, which are correspond to the experiment detection with cyclic voltammetry method.
