A New Fullerene Complexation Ligand: <i>N</i>-Pyridylfulleropyrrolidine

The subject of this paper is a new fullerene building block design with the potential for defined geometry and good electronic communication. The synthesis and characterization of a new pyridinofullerene ligand capable of forming axially symmetric complexes with metalloporphyrins is reported. X-ray structural and molecular modeling studies, 1H NMR, UV−vis spectroscopy, electrochemistry studies, and fluorescence quenching data support the formation of a strong complex between the new ligand and the metal center of ZnTPP. On the basis of computational studies, the highest occupied molecular orbital (HOMO) of this ligand is significantly different from a model compound with insulating carbons between the pyridine and the fullerene. The N-pyridinium fulleropyrrolidine salts of the new ligand and model compound were also prepared and their spectral and electrochemical properties are reported.本研究聚焦于一种新型富勒烯（fullerene）构筑基元的设计，该基元有望实现精准可控的几何构型与优异的电子耦合性能。本文报道了一种新型吡啶并富勒烯配体的合成与表征，该配体可与金属卟啉形成轴对称配合物。通过X射线晶体结构分析、分子模拟研究、核磁共振氢谱（¹H NMR）、紫外-可见（UV−vis）光谱法、电化学测试以及荧光猝灭实验数据，可证实该新型配体与四苯基锌卟啉（ZnTPP）的金属中心能够形成稳定的强相互作用配合物。基于计算模拟结果，该配体的最高占据分子轨道（HOMO）与一种在吡啶与富勒烯之间带有绝缘碳桥的模型化合物存在显著差异。此外，本研究还制备了该新型配体与模型化合物的N-吡啶鎓富勒烯吡咯烷盐，并报道了它们的光谱与电化学性能。
