| 摘 要： | 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．

| Abstract: | N, N'-bis ( 8-hydroxyquinolyl-5-methylene)-piperazine (BHQP) was synthesized andused as ligands to form a novel hyperbranched coordination polymer with aluminum ions, whichfurther self-assemblied into spherical nanoparticles. The morphology of the particles wasobserved by transmission electron microscopy (TEM) and the structure of the hyperbranchedpolymer was characterized by electrospray ionization mass spectrometry (ESI-MS). Particle sizeswere measured from TEM images and narrow size distribution was evaluated according to theimages of hundreds of particles. It was found that the formation of the nanoparticles depends onthe molar ratio of the ligands and the metal ions. Photolurninescence of the particles wasexaminned and the result was discussed. |
