利用同步X射线晶体学和1h NMR和荧光光谱技术，研究了两种三足卟啉主体在C60存在下的固态自组装。结合亲和、化学计量和几何形状强烈地依赖于卟啉宿主的大小。在共晶中观察到分子内和/或分子间卟啉-富勒烯相互作用，在每种情况下，三聚体都表现出“镊子状”结构基序。三聚富勒烯共晶的固态结构显示出紧密的富勒烯-卟啉和富勒烯-富勒烯接触。
The self‐assembly of two tripodal porphyrin hosts in the presence of C60, in the solid state, has been studied using synchrotron X‐ray crystallography, and in solution by using1H NMR and fluorescence spectroscopies. The binding affinities, stoichiometries and geometries strongly depend on the size of the porphyrin host. Intramolecular and/or intermolecular porphyrin–fullerene interactions are observed in the co‐crystallites and in each case, the trimer exhibits a “tweezers‐like” structural motif. The solid‐state structures of the trimer‐fullerene co‐crystallites reveal close fullerene–porphyrin and fullerene–fullerene contacts.
