Abstract:

Copolymer, regiorandom and regioregular poly(3-octylthiophene)-co-poly(3-(2-ethyl-1-hexylthiophene))(P3OTIOT)was synthesized by a FeCl₃-oxidation and GRIM(grignard method)approach.The structure and optical properties were verified by the Fourier transform infrared, ultraviolet visible spectroscopy, NMR(nuclear magnetic resonance), gel permeation chromatography(GPC)and photoluminescence(PL).The results indicate that the band-gap energy of the regioregular HT P3OTEHT was lower than that of the regiorandom copolymer and both of them depict low band-gap energy, high photoluminescence quantum yield, excellent solubility and processability, and might be promising polymer materials for applications in polymer light-emitting diodes, light-emitting electrochemical cells and polymer solar cells, etc.
