A series of novel dendritic carbazole-functionalized subporphyrins, T(Cz-Gn)SubPs (n = 1–3), have been synthesized from pyridine–tri(pyrrol-1-yl)borane and the corresponding aldehydes. This study has demonstrated that intramolecular energy transfer from the carbazole dendron to the subporphyrin core occurs with a high efficiency which decreases with increasing dendron generation, in accord with the
一系列新型的树枝状咔唑官能化的亚卟啉T(Cz-G n)SubPs(n= 1-3),是由吡啶-三(吡咯-1-基)硼烷和相应的醛合成的。这项研究表明,从咔唑树枝状分子到亚卟啉核心的分子内能量转移效率很高,并且随着树枝状分子生成的增加而降低,这与能量转移的Förster机制一致。另外,咔唑树突可导致亚卟啉核心的吸收和发射带发生蓝移。这些化合物的光收集能力随着世代的增加而增加。同时,这些树枝状大分子发出强烈的黄绿色光,可能是光子器件的良好候选者。(©Wiley-VCH Verlag GmbH&Co.KGaA,69451 Weinheim,Germany,2008)
