一维有机-无机异质结纳米材料因自身具有突出的光学和电学的性能而备受关注.在这种异质结材料内部,有机和无机的组分相互作用形成多个功能界面.这种新材料不仅保留了原来单组分的本征特性,还会通过界面强的作用产生新的特性,真正实现“1+1>2”的协同性能.认识和解释分子自组装的控调规律;通过分子结构的裁剪和作用力的调控实现小尺度低维分子聚集态异质结构的大面积、高有序组装;理解分子聚集态尺度下分子间弱相互作用产生的协同驱动机制和通过杂化/异质自组装优化原有功能,获得新结构的分子低维聚集态结构并在分子自组装体水平上研究结构变化导向的特殊性质,对基础科学研究的发展具有重大的科学意义.在本文中,我们主要讨论了制备异质结纳米材料的方法以及这些材料在电子和光学领域的应用.
One-dimensional organic-inorganic heterojunction nanomaterials have drawn much attention because of their outstanding optical and electrical properties, in which organic and inorganic components interact to form multiple functional interfaces. The new material not only retains the intrinsic characteristics of the original one-component, but also produces new features through the strong interface effect and realizes the synergistic performance of “1 + 1> 2” Rules; molecular structure tailoring and regulation of force to achieve small-scale low-dimensional molecular aggregation of heterogeneous structures of large-scale, high-order assembly; understanding molecular aggregation scale weak interaction between the synergy-driven mechanism and through It is of great scientific significance for the development of basic scientific research to optimize the original functions of hybrid / heterogeneous self-assembly, obtain the new low-dimensional molecular structure of molecular structure and study the special properties of structural change orientation at the molecular self-assembly level. In this paper, we mainly discuss the methods of preparing heterojunction nanomaterials and the applications of these materials in the fields of electronics and optics.
