英文摘要： In this project, we will begin with the dually sensitized luminescent coordination compounds prepared with solvent evaporation, interface diffusion, hydrothermal and solvothermal approaches, whose crystal structure and optical properties will be tuned by utilizing different sensitizing metal cations and/or functional ligands as well as changing the synthetic conditions, and then the steric structure & photophysics /chemistry will be studied in detail. Within this research, we aim to systematically uncover the intrinsic rules between the material components, structure and its physical properties, including the electron/energy transfer, photoelectric conversion, luminescent lifetime and the quantum yield. This project will give a great chance to make further comprehension of the sensitized luminescence mechanism of this kind of functional compounds, which will be helpful in both of basic principles and techniques for their potential applications. In addition, this project will make a great contribution in novel luminescent materials, owing to its essential exploration in crystal engineering, property-tuning of luminescent complex and material science.
