π-π堆积构筑超分子结构概述

Summarization on π - π Stacking Construcing Supramolecular Structures

π-π堆积是一种分子间弱相互作用,通常存在于相对富电子和缺电子的两个芳香环之间,在超分子自组装、分子识别、晶体工程等领域有广泛的应用.首先介绍了π-π堆积的本质,其次列举了利用苯环间的π-π堆积,苯环-五氟苯环间的π-π堆积及五氟苯环间的π-π堆积构筑超分子结构的实例,最后对其发展趋势做了展望.

π-π stacking is the weak intermolecular interaction, existing in two aromatic rings between relatively electron - rich and electron - deficient motif. There are a wide range of applications in the field of supramolecular self- assembly, molecular recognition, crystal engineering and so on. This paper deals with the nature of π-π stacking and the instances of π-π stacking in phenyl - phenyl, phenyl - perfluorophenyl and perflnorophenyl - perfluorophenyl complexes. And a brief outlook of treand in development of π-π stacking is also proposed.
