摘要
以对溴苯胺、巴豆醛和方酸等为原料,通过改进的Skraup-Doebner-VonMiller反应、成盐、缩合等三步反应,合成了一种方酸菁功能单体,其结构与性能利用FTIR,~1H NMR,UV及TG进行了表征。结果表明,这种溴代方酸菁在近红外区有较强的吸收以及良好的热稳定,可以应用于染料敏化太阳能电池等领域。
A functional dye,6-bromoquinaldine squaraine was designed and prepared via Skraup-Doebner-VonMiller reaction,salt formation and condensation reaction.Its structures were characterized by FT-IR,~1H NMR,UV and TG.The results showed that the resultant squaraine had strong absorption in near infared region,and showed good thermal stability as well.This squaraine product can be used in many regions,for example solar cell.
