研究目的
Investigating the combination of circularly polarized luminescence and room temperature phosphorescence in a homochiral metal–organic framework (MOF) for potential applications in optoelectronic devices.
研究成果
The study successfully demonstrated the first MOF material showing circularly polarized luminescence and phosphorescence at room temperature simultaneously. The MOF also served as an effective nanocontainer for dye encapsulation, enabling multicolor emissions including white-light emission. This opens new pathways for designing porous chiroptical materials and white-light materials for optoelectronic applications.
研究不足
The study is limited by the specific MOF structure and the dyes used for encapsulation. The practical application in devices may require further optimization for stability and efficiency under various conditions.
