title: Sol-gel conversion based on photoswitching between noncovalently and covalently linked netlike supramolecular polymers.
abstract: Photo-control over supramolecular sol-gel conversion is achieved by incorporating photoactive coumarin moieties into a tribranched monomer and the self-assembly with γ-CD followed by noncovalent-covalent switchover.
