Abstract: | A new fluorene ligand, benzo15-crown-5]-5H-pyrido3′,2′:4,5]cylopenta1,2-b]pyridin-5-ylidenehydrazone (bph), has been synthesized from the reaction of 4,5-diazafluoren-9-one
with 4′-formylbenzo-15-crown-5. The Co(II), Cu(II), and Ru(II) complexes of the ligand were prepared and characterized. The
metal-to-ligand ratio of the Co(II) and Cu(II) complexes was found to be 2:1 and that of the Ru(II) complex was found to be
1:1. The ligand and complexes have been characterized by FTIR, UV–visible, 1H NMR and fluorescence spectra, as well as elemental analyses and mass spectra. |
