有机荧光材料因其分子结构可调,材料性能优越而被广泛关注,已成为材料学、有机电子学等领域研究热点。为了获得发光颜色可控的有机荧光材料,实现其高效发光,本研究合成三种1,4-不对称苯基体系的有机荧光分子,分别在1-位引入受电子基团(Acceptor)氰基,4-位引入供电子基团(Donor)酚噻嗪、苯并咔唑或4,4-二甲氧基二苯胺,构建D-A结构有机荧光分子。进一步通过UV-Vis和荧光光谱测试其光物理性质,辅之理论计算加以验证。数据表明:通过改变1,4-位取代基,有效调控分子的HOMO-LUMO能级,调节材料的电子分布,增大了分子内电荷耦合作用,实现分子内电荷转移(Intramolecular Charge-transfer,ICt),从而实现了荧光发射从紫光(363nm)到浅蓝光(476nm)的有效调控。
