Abstract
Two discrete octahedral metallo-supramolecular cages were designed and constructed by using truxene-based pyridine L with enPd(NO3)2 or enPt(NO3)2, followed by detailed NMR, MS, UV absorption, and fluorescence spectroscopy. Owing to the determined cavity size and excellent optical performance of cages, the resulting supramolecular cages were confirmed to be the light-harvesting system based on Föster resonance energy-transfer (FRET). The developed cages display good water solubilities and can act as nanoreactors and light-harvesting systems to catalyze the difluoromethylation of quinoxalin-2(1H)-ones with sodium difluoromethanesulfinate under the irradiation of sunlight. Compared with eosin Y alone, this system displayed enhanced catalytic activity in catalyzing the difluoromethylation, which realizes the simulation of the photosynthesis process.
通过使用三萜基吡啶 L 与 enPd(NO3)2 或 enPt(NO3)2 设计和构建了两个离散的八面体金属超分子笼，并进行了详细的核磁共振、质谱、紫外吸收和荧光光谱分析。由于确定了笼子的空腔尺寸和优异的光学性能，所得到的超分子笼子被证实是基于佛斯特共振能量转移（FRET）的光收集系统。所开发的笼具有良好的水溶性，可作为纳米反应器和光收集系统，在阳光照射下催化二氟甲烷硫酸钠对喹喔啉-2(1H)-酮的二氟甲基化反应。与单独的曙红 Y 相比，该系统在催化二氟甲基化反应方面显示出更强的催化活性，实现了对光合作用过程的模拟。
