摘　　要：A new series of (E)-5-[2-(N-hexylcarbazolyl)vinyl]furan chromophores with various accepters have been synthesized by the Knoevenagel condensation of (E)-5-[2-(N- hexylcarbazolyl) vinyl]-2-furaldehydes with malononitrile, 1,3-diethyl-2-thiobarbituric acid, or 3-phenyl-5-isoxazol one, respectively. They are characterized by H-1-NMR, FT- IR, UV-VIS, MS and elemental analysis, and have shown strong solvatochromism and high thermal stability.A new series of (E)-5-[2-(N-hexylcarbazolyl)vinyl]furan chromophores with various accepters have been synthesized by the Knoevenagel condensation of (E)-5-[2-(N- hexylcarbazolyl) vinyl]-2-furaldehydes with malononitrile, 1,3-diethyl-2-thiobarbituric acid, or 3-phenyl-5-isoxazol one, respectively.
