A novel carbazole-containing Re(I) complex, Re(CO)3ClL (L = l-ethyl- 2-( N-ethyl-carbazoM-yl) imidazo[4,5-f] 1,10-phenanthroline), has been synthesized and characterized by elemental analysis, FT-IR, UV-vis, 1H NMR and emission spectroscopy, and cyclic voltammetry. The double- layer electroluminescence device of ITO/TPD (30 nm)/Re(CO)3ClL (10 nm) /Mg0.9Ag0.1 (110 nm)/Ag (60 nm) fabricated by vacuum-deposition technique was found to emit bright orange-red light with a turn-on voltage of 5 V and a maximum luminance of 113 cd/m2 at a bias voltage of 9 V.
