A dipodal receptor bearing imine linkages is decorated on the surface of ZnO nano-particles. The cation recognition properties of pure dipodal receptor are compared with the assembly having same receptor decorated on ZnO. The remarkable changes in the recognition profile are established and the ZnO coated with dipodal receptor system authenticates its use as a sensitive and selective sensor for Mg2+ in semi-aqueous medium. The ZnO coated dipodal receptor can be used to recognize the Mg2+ in cells of Saccharomyces cerevisiae. (C) 2012 Elsevier B.V. All rights reserved.
