functional molecular bridge (named as HBA-TEPIC) (HBA = 1,4-hydroxybenzoic acid, TEPIC = 3-(triethoxysilyl)-propyl-isocyanate) was achieved through the hydrogen transfer nucleophilic addition reaction. Firstly, the molecular precursors coordinate to lanthanide ions (Eu3+ and Tb3+) and then form the covalently bonded Si-O network to obtain the polymeric hybrid material (HBA-TEPIC-RE). Secondly, the synthesized
通过氢转移亲核加成反应获得了功能性分子桥(命名为HBA-TEPIC)(HBA = 1,4-羟基苯甲酸,TEPIC = 3-(三乙氧基甲硅烷基)-丙基-异氰酸酯)。首先,分子前体与镧系离子(Eu3 +和Tb3 +)配位,然后形成共价键合的Si-O网络,从而获得聚合物杂化材料(HBA-TEPIC-RE)。其次,将合成的聚合物PMMA和PMAALM以及商用PVP(聚乙烯吡咯烷酮)进一步引入到无机网络中,从而获得具有有机链和无机网络的杂化物(HBA-TEPIC-RE-PVP / PMAA / PMAALM)。规则的微观结构表明存在自组装系统,镧系元素离子和聚合物链都对杂种的生长趋势产生影响。
