Supramolecular azopolymers based on hydrogen bonds

摘要

The paper is a literature review on photoactive supramolecular polymers formed through non-covalent interactions, i.e. hydrogen bonds between azo chromophore molecules and macromolecule chains. The individual kinds of such polymers as well as the results of photoinduced optical anisotropy investigations relaed to them have been presented. The supramolecular azopolymers based on hydrogen bonds have been compared with (i) systems containing chromophores dispersed in polymer matrix, (ii) supramolecularlsystems based on ionic interactions and (iii) functionalized azopolymers. Additionally, the methods used for the identification of hydrogen bonds in supramolecular azopolymers were discussed.
