摘要: 本文以新型双萘基衍生物(NPD)作为客体分子，水溶性羧酸铵柱[5]芳烃(PA)作为主体分子，NPD与PA通过主客体相互作用在水中自组装包载荧光染料荧光桃红B (PHB)形成PA-NPD-PHB纳米粒子。PA与NPD自组装生成纳米粒子的最佳摩尔比为20:3，临界聚集浓度为0.027 mM。由于荧光染料PHB的紫外吸收区域与PA-NPD的荧光发射范围高度重合，因此在包载PHB染料后，PA-NPD的荧光发射能量可以有效地转移至PHB，成功制备了一种新型双萘基类PA-NPD-PHB人工光捕获体系。研究结果显示，该体系的能量转移效率为55%，天线效应为15，具有良好的光捕获性能，为水相人工光捕获体系的设计发展提供了新的思路和方法。
Abstract: A new bis-naphthyl derivative (NPD) was firstly prepared as guest molecules and water-soluble ammonium-carboxylate-pillar [5] arene (PA) was selected as host molecules. NPD and PA self-assemble and encapsulate fluorescent dye Phloxine B (PHB) in water through host-guest interaction to form PA-NPD-PHB nanoparticles. The optimal molar ratio for self-assembly of PA and NPD to generate nanoparticles is 20:3, and the critical aggregation concentration is 0.027 mM. Due to the high overlap between the UV absorption region of the fluorescent dye PHB and the fluorescence emission range of PA-NPD, the fluorescence emission energy of PA-NPD can be effectively transferred to PHB after encapsulating PHB dye, and a new type of artificial light-harvesting system (PA-NPD-PHB) based on double naphthalene has been successfully prepared. The research results show that the energy transfer efficiency of the system is 55%, the antenna effect is 15, and it has good light capture performance, providing new ideas and methods for the design and development of aqueous artificial light-harvesting systems.
