Abstract The pyrimidine core is present in a wide variety of compounds that show interesting fluorescent properties and have been used as pigments and dyes. In this research, we synthesized 4-(4-(dimethylamino)phenyl)-6-phenylpyrimidin-2-amine (compound 9) from chalcone (8) with 45% yield. We obtained monocrystals of 9 by slow evaporation of dichloromethane as a solvent. Additionally, we measured the
摘要
嘧啶核存在于多种化合物中,这些化合物显示出有趣的荧光特性,并已被用作
颜料和
染料。在本研究中,我们从
查耳酮 (8) 中合成了 4-(4-(
二甲氨基)苯基)-6-
苯基嘧啶-2-胺(化合物 9),产率为 45%。我们通过缓慢蒸发作为溶剂的
二氯甲烷获得 9 的单晶。此外,我们测量了化合物9的光物理性质,其吸收波长(λabs)、摩尔吸收系数(e)、激发波长(λexc)和发射波长(λem)以及斯托克斯位移(Δλ)随着增加而增加。溶剂极性。这些性质都与溶剂稳定激发态有关。另一方面,
