Abstract Water-soluble triplet sensitizer with permethyl-β-cyclodextrin (PMCD) grafting on a Schiff-base Pt(II) complex (Pt-2), in which PMCD unit serves as a host for binding the acceptors and the Schiff-base Pt(II) complex serves as a triplet sensitizer, was synthesized to investigate the effect of supramolecular complexation and assembly on the triplet-triplet annihilationupconversion emission in water
We report the synthesis and characterization of meso-anthracenylporphyrins with zinc and nickel metal centers. A variety of novel aryl and alkyl meso-substituted anthracenylporphyrins were synthesized via step-wise Suzuki cross-coupling reactions using anthracenyl boronates. This method was compared to standard syntheses based on condensation reactions to yield anthracenylporphyrins of the A2B2- and
我们报告了具有锌和镍金属中心的中间蒽基卟啉的合成和表征。使用蒽基硼酸酯通过逐步 Suzuki 交叉偶联反应合成了多种新型芳基和烷基内消旋取代的蒽基卟啉。将该方法与基于缩合反应的标准合成方法进行比较,以产生 A 的蒽基卟啉2乙2- 和一个3B型。通过 Suzuki 偶联合成许多功能化的蒽衍生物对该工作进行了补充。对选定的系统进行单晶 X 射线分析,结果显示镍 (II) 蒽基卟啉具有不寻常的紧密堆积。
