“…Metal–organic frameworks (MOFs) are porous coordination polymers with periodic network structures composed of organic ligands and inorganic metal ions/clusters. Due to the large specific surface area and tunable framework structure, MOFs exhibit attractive functional properties in gas adsorption and separation, heterogeneous catalysis, , drug delivery, and fluorescent probes. − They are also a talented platform for the CL process because the three key elements of CL (catalytic center: metal cluster; chromophore: organic ligand; controllable diffusion path: open and divisible channel) can be precisely integrated into a framework, which can be considered as an atomically precise microreactor for short energy transfer path, weaken relaxation of F, and controllable raw material diffusion rate (Scheme b). , Recently, some attempts at MOFs have been performed in CL systems. For example, Al Lawati et al loaded Rhodamine B in Co-MOF and exploited the catalytic ability of Co-MOF to promote the strong CL emission of the (H 2 O 2 )–Rhodamine B system, Li et al enhanced the luminol/H 2 O 2 CL system by constructing a hemin-bridged MOF.…”
