In this work, we have developed a novel strategy toward supramolecular polymer networks, with the utilization of molecular tweezer/guest complexation as the cross-linkages. Intermolecular O–H···N hydrogen bond is embedded in bis[alkynylplatinum(II)] terpyridine molecular tweezer/trans-azobenzene recognition motif, which could not only enhance the cross-linking strength, but also endow photoresponsiveness to the supramolecular network assemblies. Moreover, supramolecular polymer networks display intriguing singlet oxygen generation capability due to the inherent incorporation of organoplatinum(II) units. Hence, it offers a new avenue toward supramolecular materials via the combination of π-functionality, processability, and stimuli-responsiveness in an elaborate manner.
