摘要
通过非共价凹凸弱相互作用的分子间识别推动了超分子组装方式的多样性发展。电荷转移的作用增强了凹凸体之间的相互作用。富勒烯因其具有良好的凸面以及吸电子能力成为此领域研究的热点。本文以合成的碗烯(C_(20)H_(10))和C_(60)的化合物为母体设计了一系列不同大小的富勒烯球与C_(20)H_(10)的化合物体系。研究其非共价弱相互作用组成成分中凹凸作用对超分子识别和组装的作用,并且预测了不同体积的富勒烯球对此类型超分子组装体二阶非线性光学系数的影响。结果表明凹凸作用面的大小决定了体系的组装方式。另一方面,分子对称性是直接影响二阶非线性光学系数的主要因素而不是富勒烯球的体积。
Molecular recognition By non covalent concave-convex weak interaction promotes the development of a variety of supramolecular assembly way.Charge transfer were known to enhance the concave-convex interaction.Fullerene, because of its good capability of convex surface and electron withdrawing ability, is becoming a hot research in this field.In this work, based on the synthesis Hybrids between corannulene(C_(20)H_(10)) and C_(60), we designed a series of systems where different sizes of fullerenes ball connect with C_(20)H_(10).The rule of non covalent concave-convex weak interaction in the supermolecular recognition and assembly, and the influence of the different volume of fullerenes on the second order nonlinear optical coefficient of this type of supramolecular assembly body.Results show that the size of the concave and convex surfaces determines the assembly method of the system.Molecular symmetry, on the other hand, is a direct impact factor on the second order nonlinear optical coefficient instead of the volume of fullerenes ball.
