and fluorescence properties of (4-(1E,3E)-4-[4-(dimethylamino)phenyl]buta-1,3-dienyl}phenyl)methanol in different media, including organic solvents of varying polarity at 298 K, an ethanol–methanol matrix at 77 K and protein environments, have been examined. The diene shows solvatochromic fluorescence, which is correlated with empirical solvent polarity parameters. The red-shifted fluorescence emission
的电子吸收和荧光性质。 (4-(1 E,3 E)-4- [4-(二甲基氨基)苯基] buta-1,3-二烯基}苯基)甲醇 在不同的媒体中,包括自然 溶剂 在298 K时极性变化 乙醇– 77 K的甲醇基质和 蛋白质环境,已经过检查。二烯显示溶剂化变色荧光,其与经验相关溶剂极性参数。二烯的红移荧光发射归因于极性,构象松弛的分子内电荷转移激发态。此外,二烯已与牛血清白蛋白和人血清白蛋白共价连接,并且二烯的荧光探针特性蛋白质-二烯共轭物已在 磷酸盐缓冲液。
