Abstract:

A new, solution processable, thiophene copolymer with a side chain nonlinear optical NLO chromophore namely Poly3-octylthiophene-co-N-3-thenyl -4-amino-2-nitro phenol POMDT has been chemically synthesized. The copolymer was further functionalized with a photocrosslinkable cinnamoyl group, and was doped with a photocrosslinkable NLO dye. The poled, photocrosslinked, dye doped copolymer exhibited relatively large second order NLO effects d33 18.6 pmV and 3.3 pmV at 1.064 micrometers and 1.542 micrometers, respectively. The NLO properties of the photocrosslinked samples were stable at room temperature for 100 hours. The combination of reasonably good second order optical nonlinearity with established photoconducting behavior of the polythiophenes allows these type of polymers to be candidate materials in photovoltaic and photorefractive applications.
