摘要：
A new, solution-processable, thiophene copolymer with a side-chain nonlinear optical (NLO) chromophore,namely,poly(3-octylthiophene-co-N-(3-thenyl)-4-amino-2-nitrophenol) [POMDT] has been chemically synthesized. The copolymer was further functionalized with a photo-cross-linkable cinnamoyl group and was doped with a photo-cross-linkable NLO dye. The poled, photo-cross-linked, dye-doped copolymer exhibited relatively large second-order NLO effects (d33 = 18.6 and 3.3 pm/V at 1.064 and 1.542 mum, respectively). The NLO properties of the photo-cross-linked samples were stable at room temperature for 100 h.
