英文摘要: The key scientific topic of this program is to design and synthesize new metal-organic luminescent crystalline materials for multi-mode Vis-NIR modulation, energy transfer and conversion, as well as their application in opto-electronic devices such as OLEDs, opto-sensors, opto-switches and solid state solar cells. The research is focused on the design, syntheses and luminescent property study of mono/poly/hetero-nuclear lanthanide/transition metal complexes or coordination polymers. The energy transfer models and light modulations of the luminescence in these complexes in the visible and near-infrared region via the excitation of OP (one-photon), TP (two-photon) or multi-photon absorptions will be studied in detail. The target of this program is to understand the process and mechanism of the self-assembly of these crystalline materials, as well as their luminescent modulation, energy transfer, photoelectronic conversion, and device optimization, in an effort to provide the fundamentally experimental and theoretical information for controllable preparation of the metal-organic luminescent crystalline materials and pave the way for their practical applications.
