4‐difluoroboradiaza‐s‐indacene (BODIPY) dyads 1 a–1 c were designed and synthesized by the Pd‐catalyzed Sonogashira cross‐coupling reaction of ethynyl substituted NPI 1 with the meso‐, β‐, and α‐halogenated BODIPYs a, b, and c, respectively. The BODIPY 1 c exhibits redshifted absorption, which suggests better electronic communication with substitution at the α‐position of BODIPY compared with at the meso
一组1,8-萘二甲酰亚胺的(NPI) -取代的4,4- difluoroboradiaza-小号-indacene(BODIPY)二价基1 - 1c中设计并合成由乙炔基的取代的NPI的Pd-催化的Sonogashira交叉偶联反应1与内消旋- ,β-,和α-卤代BODIPYs一个,b,和ç分别。BODIPY 1 c表现出红移吸收,这表明与中观和β位置相比,BODIPY的α位置的取代具有更好的电子通信,这进一步得到了时变DFT计算的支持。光学带隙遵循顺序1 a > 1 b > 1 c。据报道,二元组1a - 1c的单晶X射线结构反映了BODIPY单元相对于NPI的平面取向。DFT优化的结构与从单晶X射线结构获得的实验数据显示出良好的相关性。1a的包装图显示了片状布置,1b形成了梯子状的结构图案,1c形成了复杂的3D结构。所述成对层1 -图1c示出低细胞毒性(IC 50 > 100μ米)。用H
