一种新型水相人工光捕获体系的构筑
The Fabrication of a Novel Aqueous Artificial LightHarvesting System
摘要: 本文设计合成了一种新型2-羟基苄基苯胺类衍生物(HPA)作为客体分子，通过与水溶性柱[5]芳烃(WP5)主客体作用，在水中形成超分子两亲体WP5⊃HPA，超分子两亲体进一步自组装形成WP5⊃HPA纳米粒子，并对染料分子磺基罗丹明101 (SR101)进行包载形成WP5⊃HPA-SR101纳米粒子。由于WP5HPA的荧光发射区域与SR101的紫外吸收有效重叠，在包载SR101后，成功构筑了一种新型水相WP5⊃HPA-SR101人工光捕获体系。值得注意的是，WP5⊃HPA-SR101的能量转移效率为48.4%，天线效应为7.8，在水相人工光捕获系统中具有潜在的应用价值。
Abstract: A novel salicylideneaniline derivative (HPA) was initially synthesized as guest molecules. After host-guest interaction with water-soluble pillar [5] arene (WP5), the formed WP5⊃HPA supramolecular amphiphile further as-sembled into nanoparticles and sulforhodamine 101 (SR101) could be encapsulated to fabricate WP5⊃HPA-SR101 nanoparticles. Because the emission region of WP5⊃HPA covers well with the UV-Vis absorption of SR101, a significant artificial light-harvesting process could take place in WP5⊃HPA-SR101 nanoparticles, which perform the energy transfer efficiency of 48.4% and the antenna effect of 7.8, suggesting potential applications in aqueous artificial light-harvesting sys-tems.
