新型金属卤化物基杂化材料的合成与光致发光性能研究

Metal halide based hybrid materials have attracted considerable interest in chemistry and materials science because of their interesting photochemical and photophysical properties. Based on the function direction principle, we will study to synthesize the photic functional metal halide based hybrid materials by using functional organic ligands and polynuclear metal halide based structure building units with photoluminescence property in this research project. In order to get new metal halide based hybrid materials with perfect optical properties, we will use special organic molecules or functional groups with outstanding optical properties to modify the frameworks, which are constructed by some organic ligands with special active sites. On the base of previous research work, we will be interested in several scientific problems as shown below: the relationship between structure and properties, the optical properties of materials, the fundamental theorem of the property mechanism, the preparation of metal halide based hybrid materials membrane, and the application in the fields of fluorescence probe, fluorescent chemosensor, biological imaging, and so on. Moreover, we will focus our most concentrated attention on some academic problem, such as single-crystal to single-crystal photochemical structural transformations and hydrothermal or solvothermal in situ organic reactions. If the research project can be successfully carried out, the research results will show the general rule of the synthesis and the relationship between structure and properties of the photic functional metal halide based hybrid materials. We will produce a series of photic functional metal halide based hybrid materials with widespread applications.
