摘要：
A new series of group 6 carbonyl complexes of N-[(2-pyridyl)methyliden]-alpha (or beta)-aminonaphthalene (alpha/beta-NaiPy) are described in this work. The complexes are formulated as cis-[M(CO)(4)(alpha/beta-NaiPy)] by elemental, mass and other spectroscopic data. The complexes show emission spectra at room temperature and their quantum yield lies between 0.4 and 0.5. All the complexes exhibit negative solvatochromism. Cyclic voltammetry shows metal centred oxidation and ligand reductions. (c) 2007 Elsevier Ltd. All rights reserved.
