摘要
超分子自组装是发展超分子电子学的重要途径。随着纳米科学和技术的迅速发展,自组装技术已成功地应用于纳米尺度物质的维数、形貌和功能等的调控。作为构筑分子水平上一维、二维、三维有序功能结构和高有序分子聚集态结构的关键技术,超分子自组装技术有力地推动了具有优良光、电、磁性能的分子材料和纳米功能材料更深层次的研究。本文综述了超分子自组装在富勒烯科学领域的基础研究和应用,特别是对有利于自组织和自组装功能的富勒烯基衍生物的设计与合成、超分子作用力引导的具有特定结构的分子体系的可控自组装、以及富勒烯分子聚集态结构材料的光物理过程、超分子中电子转移和能量转移现象进行了描述;并对卟啉、四硫富瓦烯、碗烯和杯芳烃等一系列富π电子化合物和大环主体分子等包含[60]富勒烯的主体化合物的超分子作用和超分自组装体以及通过氢键、π-π作用、静电力和范德华力和金属配位作用形成的[60]富勒烯超分子自组装体进行了总结,对未来发展进行了展望。
Supramolecular self-assembly is a significant strategy to develop supramolecular electronics. With the rapid development of nanoscience and nanotechnology, self-assembly technology has successfully been developed and applied for tuning of dimension, morphology and function of nanomaterials. As a key methodology for construction of of 1D, 2D or 3D well-defined functional nanostructures in molecular level and high ordered molecular aggregation, it pushes deeper study on optical, electronic, magnetic molecular materials and functional nanomaterials. In this paper, the fundamental studies and applications of supramolecular self-assembly, especially, design and synthesis of fullerene derivatives for benefiting self-organization and self-assembly which involve controllable supramolecular self- assembly with special structures; optical physical process in the aggregation structure of fullerene molecules; electronic and energy transfer in supramolecules were reviewed. Generally, π-rich compounds and macrocyclic host molecules, such as porphyrins, TTFs, corannulenes and calixarenes, were developed to incorporate [ 60] fullerene. Hydrogen-bonding, π-π interaction, electrostatic effects, Van der Waals force and metal-coordination, etc. were used individually or jointly to construct self-assemble nanostructures.
