Organo-clay, which is prepared by modifying clay interlayer by various organic ions, attracts attention from old time, and has been investigated and developed by many researchers because various functional organic ions can be hybridized with clay. It can be expected that broad variety of functions can be enhanced, and that functions can be upgraded, since not only clay but also various layered inorganic compounds can be used as host materials, recently. In this paper, recent movements on researches and developments of advanced materials with molecular selective adsorption and detection abilities, which are required for environmental clean-up and monitoring materials, are introduced. Additionally, luminescence change induced by adsorption of water and/or ammonia molecules to highly luminous solid material, which is recently prepared by hybridizing luminous organic dyes with layered inorganic compounds such clay and titanate nano-sheet, is introduced. And, the mechanism of luminescence change by molecular adsorption and possibility of the present materials as chemical sensor is also introduced.
