摘要

Organic-inorganic hybrid materials have been investigated in the search for new methodologies for ion recognition and sensing. As solid chemosensors, receptors immobilized onto inorganic materials such as SiO_2, Al_2O_3, and TiO_2 have important advantages in the heterogeneous solid-liquid phase: First, immobilized receptors on inorganic supports can liberate the organic guest molecules (metal ions or anions) from the pollutant solution. Second, the functionalized nanomaterials, combined with a chemodosimeter such as fluorophores or chromophores, display extremely high selectivity and sensitivity to fluorescence and absorption changes compared to spherical structures because of their larger surface areas and well-defined pores. The homogeneous porosity and large surface area of mesoporous silica make it a promising inorganic support. However, only limited examples of such heterogeneous sensors have been reported, despite the fact that they take advantage of the independent solubility properties of the receptors in water and organic solvents.
