Synthesis and Characterization of (E)-5-2-(N-hexylcarbazolyl)vinyl furan Derivatives with Acceptor Groups

摘要

A new series of (E)-5-[2-(N-hexylcarbazolyl)vinyl]furan chromophores with various acceptors 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 1H-NMR, FT-IR, UV-VIS, MS and elemental analysis, and have shown strong solvatochromism and high thermal stability.
