  A blue emission polymer: Synthesis, photophysical and electrochemical properties

  摘要：

  A novel pi-conjugated polymer (PCPyrene) containing N-benzylcarbazole and pyrene units has been synthesized and characterized. The polymer possesses high thermal stability with the decomposition temperature of 440 degrees C. It shows higher fluorescence quantum yields of in solution and solid state, respectively. PCPyrene can emit bright blue-lights both in different organic solutions (440-460 nm) and in the solid state (492 nm). Compared the emission spectra of PCPyrene in solutions with in solid state, the solid state emission of PCPyrene is significantly red-shifted. Additionally, it is not obvious changes of the solid emission spectra even after being annealed at 150 degrees C under nitrogen for 24 h. The electrochemical properties and energy levels of PCPyrene were also investigated by cyclic voltammetry. Furthermore, in order to provide a basis forecasting the structure-physical property relationships, the photophysical properties of PCPyrene have been carefully investigated by fluorescence emission and UV-vis absorption spectra.

  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.
