A new emissive mononuclear homoleptic Cu（Ⅰ） complex of 5-rert-butyl-3-（6-methyl-2-pyridyl）-1H-1,2,4-triazole（bmptzH）,[Cu（bmptzH）2]（ClO4）（1）,has been synthesized by treatment of[Cu（PPh_3）2（CH3CN）2]（C...A new emissive mononuclear homoleptic Cu（Ⅰ） complex of 5-rert-butyl-3-（6-methyl-2-pyridyl）-1H-1,2,4-triazole（bmptzH）,[Cu（bmptzH）2]（ClO4）（1）,has been synthesized by treatment of[Cu（PPh_3）2（CH3CN）2]（ClO4） or [Cu（CH3CN）4]（ClO4） with the bmptzH ligand.It is revealed that complex 1 displays a distorted N4 tetrahedral arrangement formed by two bmptzH chelates,in which bmptzH adopts a neutral bidentate chelating coordination mode using the N atom of the pyridyl ring and the 4-N not 2-N atom of the 1,2,4-triazolyl ring.It is shown that complex 1 is highly stable and exhibits good luminescence properties in solution and solid states at room temperature due to the introduction of a methyl group at the ortho-position of the pyridyl ring.展开更多
