摘要：
The synthesis, X-ray crystal structure and luminescence properties of a new bis-cyclometalated heteroleptic complex, [Ir(ppy)(2)(HD-PA)]PF6) (1, ppy = 2-phenylpyridine, HDPA = 2,2'-dipyridylamine), are reported. Both at room temperature and 77 K, complex 1 exhibits intense blue emission, assigned as (MLCT)-M-3 [d pi(Ir)pi*(HDPA)] phosphorescence. Analysis of voltammetric data also provides evidence in support of this assignment. (c) 2006 Elsevier B.V. All rights reserved.
