By incorporating an anthracene moiety into a framework, a multiresponsive luminescent metal–organic framework (1) has been synthesized, which exhibits both direct chemiluminescence (CL) and dual tunable photoluminescence. By utilizing the CL, 1 has been explored as a selective visual sensor for hydrogen peroxide. Moreover, 1 also exhibits tunable fluorescence response toward different analytes. For electron‐rich aromatics, “turn‐on” and “turn‐off” responses can be simply switched by varying the excitation wavelength. For nitroaromatics, 1 exhibits novel linear quantitative quenching response. Density functional theory (DFT) calculations and experiments have been carried out to study the unique fluorescence response. The multiple luminescence properties and dual tunable sensing response indicate that incorporating anthracene moieties into frameworks should be a promising strategy to develop unprecedented luminescent materials with remarkable sensing properties.
A novel approach integrates the hetero-interfacial charge carrier management, the photothermal excitation of the carbon sphere core and the injection of hot electrons into the TiO2 shells, consequently enhancing the visible light driven catalysis.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
