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.

Key words: self-assembly, photochemistry, fluorescentprobe, regulation of self-assemly structure
