摘要:

利用光照引发的光化学变化,作为一种通过宏观手段向微观系统提供能量和外加刺激的理想手段,在分子自组装研究中起到了重要的作用.通过光化学变化可以实现对分子自组装结构从分子结构到微观结构,再到宏观性质的多层级调控.反之,通过其他手段调节聚集体的组装结构和分子排列,也可以控制改变聚集体的发光情况.此外,分子荧光探针为认识纳米尺度的分子自组装结构的微观环境提供了有力的支持,是研究自组装结构中不可取代的重要表征手段.本文就光化学手段对分子自组装结构的调控与探测,以及自组装结构对发光分子的光学性质的影响等方面进行了介绍.

Abstract:

Photochemical changes which induced by light irradiation is an ideal method to provide energy and external stimuli to microscopic systems via macroscopic means. This method is plays an important role in the research area of molecular self-assembly. By using photochemical methods multi-level regulation to the molecular self-assemblies can be realized from molecular level to microscopic structure, and finally macroscopic properties. On the other hand, the luminescence of aggregates can be controlled by regulating the assembly structure and the molecular arrangement via other methods. After all, molecular fluorescence probes provide vigorous supports to explore the imformations of the nanometer-scaled molecular self-assemblies which is an important method in research of self-assembled structures. In this paper, we review the above areas of application of photochemical methods in regulation and exploration of molecular self-assembly and the aggregate structure-related luminescence changes.
