2-3-cyano-4-[(E)-2-(2-hydroxyphenyl)ethenyl]-5,5-dimethylfuran-2(5H)-ylidene}propanedinitriles which were found to exhibit solid state fluorescence with the emission maxima ranging from λ 594 to 640 nm. Chromophores containing an alkyl substituent in the benzene ring showed the most intense fluorescence.
在乙酸铵存在下,5-取代的2-羟基苯甲醛与2- [3-氰基-4,5,5-三甲基呋喃-2(5 H)-亚烷基]丙腈(三氰呋喃)在乙醇中反应,得到2- 3-氰基-4-[(E)-2-(2-羟基苯基)乙烯基] -5,5-二甲基呋喃-2(5 H)-亚烷基}丙二腈,显示出固态荧光,发射最大值在λ594范围内到640 nm 在苯环中含有烷基取代基的发色团显示出最强的荧光。
