Supramolecular polymer has been the hotspot in the field of supramolecular chemistry, polymer chemistry and material chemistry which has received unprecedented support from a growing number of scientific researchers. Supramolecular polymers are defined as highly directional and ordered polymeric arrays of monomeric units which are brought together by reversible noncovalent interactions including hydrogen bonding, host-guest recognition, donor-acceptor interaction, metal-ligand coordination, and n-n stacking. Photo-responsive functional groups are incorporated into supramolecular polymer systems to obtain photo-responsive supramolecular polymers, which could efficiently combine the unique characteristics of supramolecular polymer and the advantages of photochemical reactions in order to construct novel photochromic materials. Supramolecular polymer chemistry now comprises broad researching areas including main-chain supramolecular polymers and side-chain supramolecular polymers, as well as hierarchical structures. This monograph reviews the recent progress on photo-responsive supramolecular polymers in our group. Specifically, photo-switching between monomer/oligomer and supramolecular polymers constructed via cyclodextrin, cucurbituril and bis-p-sulfonatocalix[4]arene host recognition were illustrated respectively, together with such various functions as photochromism, aggregation-induced emission, gelation, and so forth. Covalent/noncovalent bond transitions in linear and netlike supramolecular polymers were introduced in details, typically via the photo-induced reversible dimerization reaction of such photo-active groups as coumarin, anthracene, stilbene etc. Photo-responsive reversible morphology transitions of supramolecular polymers realized via photo-responsive reversible chiral morphology transition via cyclodextrin including azobenzene group and those containing chiral binaphthol group in the system, photochrosim and isomerization of the groups in the system. Other functional supramolecular polymers based on the supramolecular interactions in the side chains, like self-healing property realized by the host-guest interaction between the cyclodextrin and bromonaphthalene moieties on their side chains, and cyclodextrin host and hydrogen bonding induced room temperature phosphorescence emission, were also well introduced. Finally, comments and some prospects were given on the future research of the supramolecular polymers as well.
