We report the construction of three structurally distinct self-assembled architectures: FeL pseudoicosahedron , FeL helicate , and FeL tetrahedron , formed from a single triazatriangulenium subcomponent under different reaction conditions. Pseudoicosahedral capsule is the largest formed through subcomponent self-assembly to date, with an outer-sphere diameter of 5.4 nm and a cavity volume of 15 nm. The outcome of self-assembly depended upon concentration, where the formation of pseudoicosahedron was favored at higher concentrations, while helicate exclusively formed at lower concentrations. The conversion of pseudoicosahedron or helicate into tetrahedron occurred following the addition of a CBH or BF template.
FeL 拟二十面体、FeL 螺旋体和 FeL 四面体，它们由单个三嗪三角烯亚组件在不同的反应条件下形成。假二十面体胶囊是迄今为止通过亚组件自组装形成的最大的，其外径为 5.4nm，腔体积为 15nm。自组装的结果取决于浓度，其中在较高浓度下有利于形成拟二十面体，而螺旋体仅在较低浓度下形成。在添加 CBH 或 BF 模板后，拟二十面体或螺旋体转化为四面体。
