Preparation of Luminous Dyes/Layered Double Hydroxide Nano Hybrid with Molecular Detection Ability

Abstract

Layered double hydroxide (LDH: M^<II>_<1-x>M^<III>_x(OH)_2(A^<n->)_<x/n>・mH_2O (M^<II> & M^<III>: divalent and trivalent metals) is anion exchangeable clay, and is widely used as inorganic host for solidifying and/or fixing a physiologically active and functional anions. Authors have been studying on the preparation and characterization of the LDH/luminous dye anions. Recently, it was found that luminous properties of dye anions incorporated in 2-dimensional interlayer space of LDH by anion exchange reaction changed depending on surrounding environment. In this paper, authors introduce the way to prepare the LDH/luminous dye anions with highly luminous property and environmental luminous response of the present sample for surrounding environment.
