合成了N,N′-双(8-羟基喹啉基-5-亚甲基)哌嗪,并与铝离子配位形成了新颖的超支化配位聚合物,进而自组装成了球形纳米粒子.超支化聚合物的结构和纳米粒子的形态分别通过ESI-MS和TEM证实.粒子的大小及其分布通过测量TEM照片上的数百个粒子得到,结果表明粒子的大小分布较窄.同时发现纳米粒子形成依赖于配体和铝离子的比例.我们测定了这种配位聚合物纳米粒子的光致发光性质,并对结果进行了讨论.
Synthesis of N, N’-bis (8-hydroxyquinolyl-5-methylene) piperazine and aluminum ions coordinated to form a novel hyperbranched coordination polymer, and then self-assembled into spherical nanoparticles The structure of the hyperbranched polymer and the morphology of the nanoparticles were confirmed by ESI-MS and TEM respectively.The size and distribution of the particles were obtained by measuring hundreds of particles on a TEM photograph, showing a narrower particle size distribution. Nanoparticle formation depends on the ratio of ligand to aluminum ion.We measured the photoluminescence properties of this coordination polymer nanoparticle and discussed the results.
