Fuller-rylenes is a useful model to tailor the properties of cross-dimensional molecular carbons to define their scope for specific applications. Herein we present a straightforward synthetic strategy to hybridize planar rylene dyes and spherical fullerene into esthetic nanostructures containing features from both subunits via one-pot Pd-catalyzed [3 + 2] or [4 + 2] cyclization reactions. Single-crystal X-ray diffraction analysis revealed conclusively the molecular configurations and distinct self-assembly crystal arrangements resulting from the different extension directions of the planar π-systems on the fullerene ball. Our strategy allowed for easy structural and electronic variations; especially, the lowest unoccupied molecular orbital (LUMO) and highest occupied molecular orbital (HOMO) orbital profiles of the two fuller-rylenes, namely, Fuller-PMI and Fuller-PDI (where PMI refers to as perylene monoamide, and PDI, perylene diimide) molecules, determined by combining fullerene with perylene, which featured different edge structures.

富勒烯:多维分子碳

富勒烯是一个有用的模型,可用于调整横向分子碳的特性,以定义其特定应用范围。在这里,我们提出了一种简单的合成策略,即通过一锅Pd催化的[3 + 2]或[4 + 2]环化反应,将平面萘嵌苯染料和球形富勒烯杂化成包含两个亚基特征的美学纳米结构。单晶X射线衍射分析最终显示了富勒烯球上平面π系统的不同延伸方向所导致的分子构型和不同的自组装晶体排列。我们的策略允许轻松进行结构和电子变化;特别是两个富勒烯的最低未占据分子轨道(LUMO)和最高占据分子轨道(HOMO)轨道剖面,即
