Zhang JF, Fu WF, Gan X, Chen JH: Synthesis, structures and photophysical properties of luminescent copper (I) and platinum (II) complexes with a flexible naphthyridine-phosphine ligand. Dalton Trans. 2008 Jun 21;(23):3093-100. Epub 2008 Apr 30.
Condensation of Ph (2) PH and paraformaldehyde with 2-amino-7-methyl-1,8-naphthyridine gave the new flexible tridentate ligand 2-[N-(diphenylphosphino) methyl] amino-7-methyl-1,8-naphthyridine (L). Reaction of L with [Cu (CH (3) CN)(4)] BF (4) and/or different ancillary ligands in dichloromethane afforded N,P chelating or bridging luminescent complexes [(L)(2) Cu (2)](BF (4))(2), [(micro-L)(2) Cu (2)(PPh (3))(2)](BF (4))(2) and [(L) Cu (CNN)] BF (4) (CNN = 6-phenyl-2,2'-bipyridine), respectively. Complexes [(L)(2) Pt] Cl (2), [(L)(2) Pt](ClO (4))(2) and [(L) Pt (CNC)] Cl (CNC = 2,6-biphenylpyridine) were obtained from the reactions of Pt (SMe (2))(2) Cl (2) or (CNC) Pt (DMSO) Cl with L. The crystal structures and photophysical properties of the complexes are presented. |
