Microstructures of fullerene derivatives formed self-assembly strategy facilitate the versatile applications of these zero-dimensional molecules. However, the accurate elucidation of formation mechanism of fullerene microstructures is a challenge issue. A novel fullerene derivative 2 with rigid pyridine substituent was synthesized and characterized by X-ray crystallography. Using the strategy of liquid-liquid interfacial precipitation, self-assembly of 2 affords a micrometer-sized flowerlike and a discoid morphology. Based on the crystal packing of 2, the proper formation mechanism of different morphologies was proposed. Meanwhile, the photoelectrochemical properties of different morphologies of 2 was also unveiled.
富勒烯衍生物的微观结构形成的自组装策略促进了这些零维分子的广泛应用。然而，准确阐明富勒烯微观结构的形成机制是一个具有挑战性的问题。合成了一种具有刚性吡啶取代基的新型富勒烯衍生物2，并通过X射线晶体学对其进行了表征。采用液-液界面沉淀策略，2的自组装产生了微米级的花状和盘状形态。基于2的晶体堆积，提出了不同形态的适当形成机制。同时，还揭示了2不同形态的光电化学性质。
