Emissive Osmium(II) Complexes with Tetradentate Bis(pyridylpyrazolate) Chelates

Shih-Han Chang, Chun-Fu Chang, Jia-Ling Liao, Yün Chi et autres

A tetradentate bis(pyridylpyrazolate) chelate, L, is assembled by connecting two bidentate 3-(trifluoromethyl)-5-(2-pyridyl)pyrazole chelates at the 6 position of the pyridyl fragment with a phenylamido appendage. This chelate was then utilized in the synthesis of three osmium(II) complexes, namely, [Os(L)(CO)2] (4), [Os(L)(PPh2Me)2] (5), …
