Imine linked 1,8-naphthalimide: Chromogenic recognition of metal ions, density function theory and cytotoxic activity

The naphthalimide-based and imine coupled receptor has been synthesized and this receptor is evaluated for metal recognition properties. The Cu2+ and Co2+ recognition in the coordination sphere of receptor leads to a change in the photo-physical properties of receptor. The receptor and its metal complexes are evaluated for the cytotoxic activities and studies have led to construction of the molecular logic gate. (C) 2012 Elsevier B.V. All rights reserved.
