quantum yield and molar absorptivity. The aggregation of these cyanine dyes was studied and compared to a similar series of symmetric cyanine dyes. It was determined that the heterocycle has more effect on aggregation than the side chain and a dye with two different heterocycles will aggregate less than a dye with the same heterocycle. The dyes were also investigated for Lipinski Rule violations as their

染料是一类有机化合物,其中包含两个杂环,这些杂环充当通过共轭次
甲基桥连接的电子供体和受体。本文报道了一系列16种新型不对称
三甲胺花青染料的合成。通过各种光谱技术表征了它们的结构,并测量了它们的光学性质。使用随时间变化的密度泛函理论方法计算
染料的吸收最大值,并且计算的吸收最大值与实验数据一致。在杂环上添加吸电子取代基例如卤素给出了更有利的光学性质,例如更高的量子产率和摩尔吸收率。对这些
花青染料的聚集进行了研究,并将其与类似系列的对称
花青染料进行了比较。已确定杂环比侧链对聚集的影响更大,并且具有两个不同杂环的
染料的聚集将比具有相同杂环的
染料的聚集少。还研究了这种
染料是否违反Lipinski规则,因为它们的使用越来越普遍。体内应用。
