Abstract

Abstract: Enabling dynamically tunable emissive systems offers opportunities for constructing smart materials. Clusteroluminescence, as unconventional luminescence, has attracted increasing attention in both fundamental and applied sciences. Herein, we report a supramolecular poly(disulfides) network with tunable clusteroluminescence. The reticular H‐bonds synergize the rigidity and mobility of dynamic networks, and endow the resulting materials with mechanical adaptivity and robustness, simultaneously enabling efficient clusteroluminescence and phosphorescence at 77 K. Orthogonally tunable luminescence are achieved in two manners, i.e., slow backbone disulfide exchange and fast side‐chain metal coordination. Further exploration of the reprocessability and chemical closed‐loop recycling of intrinsic dynamic networks for sustainable materials is feasible. We foresee that the synergistic strategy of dynamic chemistry offers a novel pathway and potential opportunities for smart emissive materials. Abstract : The dynamic synergy strategy provides a novel example of supramolecular dual‐tunable clusteroluminescence. The unique β‐sheet conformation endows materials with efficient luminescence as well as mechanical adaptivity and robustness. Moreover, dual dynamic polymeric networks provide an ideal platform for the orthogonal regulation of clusteroluminescence and chemical closed‐loop recycling.
