Based on the self-assembly of the pyrazolone ligand HPMIP (1-phenyl-3-methyl-4-(isobutyryl)-5-pyrazolone), DyCl3·6H2O and/or the 5-Br-2,2′-bpy (5-bromo-2,2′-bipyridine), two tris-pyrazolonate-Dy3+-complexes [Dy(PMIP)3(H2O)2] (2) and [Dy(PMIP)3(5-Br-2,2′-bpy)] (5) characteristic of dual-emissive emissions toward single-mol. white-light are obtained, resp., and in dependence on the effective suppression from the oscillator-induced quenching by the involved 5-Br-2,2′-bpy, the color-compensation of the residual ligands-based strong emission and the Dy3+-centered (4F9/2 → 6HJ/2 transitions) multiple emissions renders its Dy3+-complex an efficient (Φem = 4.2%) single-mol. white-light. The experimental part of the paper was very detailed, including the reaction process of 2,5-Dibromopyridine(cas: 624-28-2COA of Formula: C5H3Br2N)
2,5-Dibromopyridine(cas: 624-28-2) belongs to pyridine. Pyridine derivatives lend themselves to many roles in the spirited field of supramolecular chemistry – whether as the ligand backbone of metal-organic polymers or presiding over the key electronic stations of nanodevices. In biochemistry, pyridine-containing cofactors are necessary nutrients on which our lives depend. COA of Formula: C5H3Br2N
