Electrosynthesis, Characterization, Thermal, Optical, Electrochemical Properties and Conductivity of Conjugated Oligomers Bearing Pyrenyl Groups

摘要

In this paper, we report the electrochemical polymerization of 1-ethynylpyrene (EP), 1-(but-1-yn-3-enyl)pyrene (BP) and 1-(4-trimethylsilanylbuta-1,3-diynyl)pyrene (TMSBDP). The obtained oligomers were characterized by FTIR and NMR spectroscopies. Thermal properties of these compounds were determined by thermogravimetric analysis and differential scanning calorimetry, and their optical properties by absorption and fluorescence spectroscopies. Electrical conductivity of the oligomers was measured in the doped state.
