Visible-light harvesting cyclometalated Ir(III) complexes were used as ¹O₂ sensitizers for the photooxidation of 1,5-dihydroxynaphthalene (DHN) and substantially improved photooxidation capability was observed compared to the conventional Ir(III) complex sensitizers that show no visible light-harvesting capabilities.

Here a novel fluorescent supramolecular cross-linked polymer network with aggregation induced enhanced emission (AIEE) properties was constructed via pillar[5]arene-based host–guest recognition. Furthermore, the supramolecular polymer network can be used for explosive detection in both solution and thin films.
