Dibenzoylmethane (dbm) initiators with one and two alcohol sites were used to generate dbm end-functionalized and dbm-centered poly(ε-caprolactone) macroligands (dbmPCL and dbmPCL2) with low polydispersities (∼1.1). Chelation of polymeric ligands to metal ions (Eu3+, Fe3+, Ni2+ and Cu2+) produced metal-centered star polymers, which were characterized by UV–vis and fluorescence spectroscopy, as well
具有一个和两个醇位的二苯甲酰甲烷(dbm)引发剂用于生成具有低多分散度(〜1.1)的dbm末端官能化和dbm中心的聚(ε-己内酯)大配体(dbmPCL和dbmPCL 2)。聚合物配体与金属离子(Eu 3+,Fe 3+,Ni 2+和Cu 2+)的螯合产生了以金属为中心的星形聚合物,其特征在于紫外可见光谱和荧光光谱以及凝胶渗透色谱法。
