基于稀土金属离子配位超分子聚合物的荧光微囊
以基于金属配位作用的聚合物材料Eu-L2EO4为带负电的聚电解质, 利用静电相互作用通过层层组装的方法制备了自发光的聚合物荧光微囊. 该微囊壁孔径很小, 对小分子负载具有良好的封闭性, 且在盐浓度高达500 mmol·L-1时依然稳定, 表现出良好的耐盐性质. 以Eu3+-Tb3+混合离子取代Eu3+, 可以制备多色荧光微囊.

Fluorescent Microcapsules Based on Coordination Supramolecular Polymers of Rare Earth Metal Ions
Fluorescent microcapsules based on coordination supramolecular polymers of rare earth metal ions were prepared via a layer-by-layer technique that used electrostatic interaction. The holes in the capsule walls were very small, which reduced leakage of small molecular payloads. The capsules remained intact at salt concentrations as high as 500 mmol·L-1, which shows they have potential in practical applications. Multicolored capsules were obtained simply using a mixture of terbium and europium ions.
