| 摘 要： | 本文基于分子间质子转移和诱导分子内电荷转移（ICT）机理，合成了以萘酰亚胺为发光基团、苯甲酰为F-检测基团的荧光单体，并采用可逆加成-断裂链转移（RAFT）聚合方法将其与N-异丙基甲基丙烯酰胺（NIPAM）进行共聚，制备了一种可以用于F-检测的共聚物荧光探针poly（NIPAMm-co-Napn）（简称PNap334），并分别在二氯甲烷-二甲基亚砜（9/1，V/V）溶液和固体薄膜中考察了聚合物PNap334对F-的响应。研究发现，聚合物溶液和聚合物膜对F-均有很好的识别作用，聚合物溶液对F-的检测限为1.05 μmol/L。

| Abstract: | Polymeric fluorescent chemosensor, poly(NIPAMm-co-Napn) (abbreviation as PNap334), has been synthesized by reversible addition-fragmentation chain transfer (RAFT) polymerization. The copolymer consists of 1,8-naphthalimide as luminophore and benzamide as fluoride ions (F-) selective detection unit. The F-responsive properties of the resulted copolymer PNap334 were investigated in DCM/DMSO (9/1, V/V) solution and film, respectively. Based on an intermolecular proton transfer (IPT) and induced intramolecular charge transfer (ICT) mechanism, the polymeric chemosensor displays distinct selective detection of F- both in solution and film. And the detection limit of F- in solution is 1.05 μmol/L. |
