合成了单体甲基丙烯酸-2-(9,9-二乙基)芴甲酯(FMMA)作为捕光天线分子,通过原子转移自由基聚合方法(ATRP)合成了以β-环糊精(β-CD)为核的21臂星形发光聚合物β-CD-g-(PFMMA-b-PDMAEMA)21作为捕光聚合物.通过氢核磁共振谱、基质辅助激光解析电离飞行时间质谱和凝胶渗透色谱对其结构进行了表征.将其与能量受体分子蒽包合,通过紫外-荧光测试检测到了两者的能量传递现象,成功证明了基于主客体包合作用的星形拓扑分子捕捉和传递能量的过程,在光敏器件、太阳能电池和有机发光二极管等领域内具有潜在的应用价值.
(FMMA) was synthesized as the light-harvesting antenna molecule. A novel method of synthesizing β-cyclodextrin (β-cyclodextrin) was synthesized by atom transfer radical polymerization (ATRP) β-CD) was used as light-harvesting polymer, and the 21-arm star-shaped luminescent polymer β-CD-g- (PFMMA-b-PDMAEMA) 21 was identified by proton nuclear magnetic resonance spectroscopy, matrix-assisted laser desorption ionization time of flight mass spectrometry Its structure was characterized by gel permeation chromatography.The energy transfer phenomenon was detected by UV-fluorescence and the star-shaped topological molecule based on host-guest inclusion was successfully captured And the transfer of energy in the process of photosensitive devices, solar cells and organic light-emitting diodes and other fields have potential applications.
