An L-glutamide-functionalized tetraphenylporphyrin () has been newly synthesized and its self-assembling behavior in organic solvents is reported. forms nanofibrous assemblies in a dilute solution to show specific induced circular dichroism at the absorption band around the porphyrin moiety. It enables us to observe the meso-stable and stepwise H- and J-like hierarchical aggregations. Energy transfer studies in a mixed system with a pyrene-functionalized L-glutamide reveal the promotion of energy transfer from the pyrene excimer to the porphyrin moiety.
一种新合成的L-谷氨酰胺功能化四苯基卟啉()及其在有机溶剂中的自组装行为被报道。在稀溶液中形成纳米纤维聚集体,在卟啉部分周围的吸收带处显示出特定的诱导圆二色性。这使我们能够观察到介稳且逐步的H型和J型分层聚集。在与芘功能化L-谷氨酰胺的混合体系中的能量转移研究揭示了从芘准分子到卟啉部分的能量转移促进作用。
