The photorefractive composites fabricated by blending NLO chromophores such as 3-(4-{bis-[4-(2-ethylhexyloxy)-phenyl]-amino}-phenyl)-2-isocyano-acrylonitrile (PAIA), bis-[4-(2-ethyl-hexyloxy)-phenyl]-{4-[2-(4-nitrophenyl)-vinyl]-phenyl}-amine (PNPA) with photoconducting crosslinkable matrix, bis-(4-ethynylphenyl)-(4-octyloxyphenyl)-amine (BEOPEA), showed photorefractive property due to the high composition of NLO chromophores caused by introducing alkoxy chain, and many problems faced in typical organic photorefractive systems such as timeconsuming chemical synthesis, difficulty in rational design, intrinsic instability and phase separation could be avoided.
