The synthesis of 2-(2-arylvinyl)- and 2,6-di(2-arylvinyl)dibenzo[1,2-b:4,5-b′]furan derivatives for application in optoelectronics is described. Wittig reaction of the triphenylphosphonium bromides derived from diethyl 2,6-dimethylbenzofuro[5,6-b]furan-3,7-dicarboxylate with aryl aldehydes gave the products in 70–99% yield. The corresponding products derived from furfural and cinnamic aldehyde were
描述了用于光电子学中的2-(2-芳基乙烯基)-和2,6-二(2-芳基乙烯基)二苯并[1,2- b:4,5- b' ]呋喃衍生物的合成。由2,6-二甲基苯并呋喃[5,6-b]呋喃-3,7-二羧酸二乙酯衍生的三苯基溴化与芳基醛的Wittig反应制得的产物收率为70-99%。还获得了衍生自糠醛和肉桂醛的相应产物。所制备的产品显示出UV-Vis荧光,其量子产率在1%至100%之间,可以用作有机发光器件(OLED)的有机小分子材料。
