一锅法制备pH响应性聚丙烯酰基乙二胺盐酸盐-卟啉/芴荧光聚合物
Preparation of pH-Sensitive Fluorescent Poly(acryl-2-aminoethy- lammonium hydrochloride) with Porphyrin or Fluorene by One-pot Method
摘要
Abstract
Poly ( N-tert-butoxycarbonyl-N’-acryloyl-1 , 2-diaminoethane ) ( PBAEN ) with dithioester as end groups was prepared via reversible addition-fragmentation chain transfer polymerization(RAFT). The one-pot method, which the reduction of dithioester and Click reaction between thiol and epoxy group were conducted simultaneously, was used to prepared fluorescently label poly( N-acryloyl-1,2-diaminoethane hydrochloride)-porphyrin(PAEN-EPT) and poly(N-acryloyl-1,2-diaminoethane hydrochloride)-fluorene(PAEN-DEPF). The fluorescence intensity of PAEN-EPT and PAEN-DEPF in aqueous solution decreased dramatically as pH≥7 due to the polymer chain shrinking. The PAEN-EPT and PAEN-DEPF showed the pH-response. In addition, the quantum yield for PAEN-EPT aqueous solution could reach 0. 096.关键词
