Synthesis of ferrocene based comb-shaped polymers and its anion recognition

利用二茂铁单甲酸与草酰氯反应合成二茂铁甲酰氯,再以二茂铁甲酰氯与丙烯酸羟乙酯为原料合成丙烯酸二茂铁甲酰氧基乙酯,然后由聚乙烯醇与2-溴异丁基酰溴反应合成原子转移自由基聚合(ATRP)引发剂,引发丙烯酸二茂铁甲酰氧基乙酯进行ATRP聚合.制备了具有梳型结构的聚合物,并对产物进行红外表征,研究聚合物在离子识别方面的应用.结果表明:梳型聚丙烯酸二茂铁甲酰氧基乙酯成功合成,对阴离子H2PO4-有很好的识别能力.

Ferrocenyl formyloxyl chloride was synthesized through the reaction of ferrocene carbonate acid with oxalyl chloride, then ferrocenyl formyloxyethyl acrylate was prepared using ferrocenyl formyloxyl chloride and acrylic hydroxyl ethyl ester as raw materials. Moreover, the initiator of ATRP was produced by the reaction of poly (vinyl alcohol) with 2-bromine isobutyl bromine, then initiated ATRP polymerization of ferrocenyl formyloxyethyl acrylate and produced the comb-shaped polymer of ferrocenyl formyloxyethyl acrylate. The comb-shaped polymer was characterized by infrared spectrometer and applied in cation recognition. The results showed that the polymer of ferrocenyl formyloxyethyl acrylate was successfully synthesized and provided with high anion recognition capacity of H 2 PO 4-.
