Macrocylic dicarbinolamine nickel (II) complexes with diimine moiety in their ligand exhibited luminescence, when irradiated at their charge transfer band. The Stern-Volmer (S-V) plots of one of the complexes in DMF medium exhibited positive curvature, when FeCl3 was used as a quencher, while the same complex showed negative curvature when nitrobenzene was used as a quencher. The mechanism for the luminescence quenching of the macrocyclic complex has also been discussed. (C) 2003 Elsevier B.V. All rights reserved.
