摘要：A new strategy for phototriggered supramolecular polymerization of the [c2] daisy chain is demonstrated. A daisy chain rotaxane containing two coumarin protected 2-ureido-4-pyrimidinone (Upy) terminals at two ends was designed, whose supramolecular polymerization can be initiated by light irradiation that can remove the photocleavable protecting coumarin groups and uncage the two terminal Upy functional units.
