| Abstract: | The synthesis, X-ray crystal structure and luminescence properties of a new bis-cyclometalated heteroleptic complex, [Ir(ppy)2(HDPA)](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 3MLCT [dπ(Ir)-π∗(HDPA)] phosphorescence. Analysis of voltammetric data also provides evidence in support of this assignment. |
