【摘要】：二维有机组装体是一类具有特殊形貌和性质的有序结构,有可能带来新功能和光电子领域的潜在应用,但如何实现二维有机组装体的可控制备是尚待解决的问题.针对这一问题,我们通过对构筑基元的理性设计,调控分子间的相互作用,发展了三种可控制备二维有机组装体的新方法:(1)利用疏水有机阴离子作为Bola型两亲分子的抗衡离子,能够削弱亲水头基间的静电排斥作用,从而诱导两亲分子的组装结构从一维向二维转变;(2)基于非共价键形成超两亲分子,通过设计和控制超两亲分子的拓扑结构,简便有效地实现二维组装体的制备;(3)通过共价修饰或引入新的非共价键,以限制三维结构在某一方向上的生长,从而降低三维结构的维度,也能实现二维组装体的可控制备.未来,上述研究有望进一步拓展,并实现功能二维有机组装体的构筑.
[Abstract]:A two-dimensional assembly body is a kind of special morphology and properties of the ordered structure, may bring new features and potential applications of optoelectronics, but how to achieve a two-dimensional unit assembly controlled preparation is a problem to be solved. To solve this problem, we construct a rational design based on basic element, each other interactions between molecules, the development of three kinds of controllable preparation of a new method of two-dimensional unit assembly: (1) the use of hydrophobic organic anions as Bola type two amphiphilic molecules of counterions, can weaken the pro electrostatic repulsion between head groups, thus inducing assembly structure of two amphiphilic molecules changed from one-dimensional to two-dimensional; (2) two amphiphilic molecules form a non covalent bond based on topological structure of super two amphiphilic molecules through the design and control of the simple and effective implementation of 2D assembly preparation; (3) through covalent modification or introduction of new non covalent bond, to limit three The growth of dimension structure in a certain direction can reduce the dimension of three-dimensional structure and control the preparation of two-dimensional assembly. In the future, the above research is expected to further expand, and achieve the construction of functional two dimensional assembly.
