摘要
The synthesis, structure, and photoluminescence properties are described for the three-coordinate mononuclear and dinuclear complexes [H2B(3,5-(CF3)(2)PZ)(2)]M(2,4,6-collidine), M-1, and {[3,5-(CF3)(2)Pz]M(2,4,6-collidine)}(2), M-2, respectively (M = Cu; Ag). The solids exhibit bright blue phosphorescence, at room temperature for the copper compounds and at 77 K for all compounds. Ag-1, Cu-1, and Cu-2 exhibit blue pyrazole-based structured emissions with short phosphorescence lifetimes, 10(1)-10(2) mus, due to an internal heavy-metal effect. Meanwhile, Ag-2 exhibits curious multiple excitation-dependent emissions.
