Coordinate Anchoring of Mixed Luminophores in Two Isostructural Hybrid Layers to Achieve Tunable Room-Temperature Phosphorescence

“…The first is the rigid carboxylate derivative ligands. The anchoring of various carboxylate luminophores with metal ions generates diverse MOC-based RTP materials. − For example, anchoring rigid dicarboxylate derivatives such as terephthalic acid with d 10 -metal ions produce a series of MOCs with fascinating RTP performance. − Besides the carboxylate derivatives as luminophores, polydentate N ligands such as polyimidazole derivatives are also utilized as potential luminophores to build MOC-based RTP materials. − Although successive progress has been gained in anchoring polydentate luminophore ligands in MOC systems to achieve RTP materials, the development of new MOC systems with tunable RTP functionality is still challenging.…”

“…Notably, tunable RTP properties were available via changing the categories of protonated organoamines. Paralleling the polydentate O ligands as luminophores, the locking of a triimidazole derivative in the metal–phosphite system produces assorted MOC-based RTP materials, and the RTP functionalities could be modulated via altering the categories of coordinated halogen ions and guest species. − Reviewing the references of MOC-based RTP materials implies that most of the products feature a single luminophore ligand. − Therefore, the locking of mixed luminophores in MOC systems may offer an avenue to modulate RTP performance of resulting isostructural products via ligand-directed substitution synthesis. As our continuous investigations on the generation of MOCs bearing tunable RTP properties, we, herein, anchored mixed luminophores, polydentate N ligand (1,3,5-tris­(2-methyl-1 H -imidazol-1-yl)­benzene, TIMB) and polydentate O ligands (2,5-dichloroterephthalic and 2,5-dibromoterephthalic acid, H 2 -X 2 -TPA), to produce isostructural MOCs, [Zn­(TIMB)­(X 2 -TPA)]·H 2 O ( 1 , X = Cl; 2 , X = Br), and modulate the RTP performances of resultant MOCs via the synergy of coordinate anchoring and substitution synthesis.…”
