通过将铕（Eu（III））离子引入到星星聚合物的核中来开发水溶性发光材料。采用活性自由基聚合法合成了星星型聚合物。研究了以聚甲基丙烯酸甲酯为臂将Eu（III）离子引入到星星型聚合物中的策略，发现采用同时引入的方法可以获得最佳的Eu（III）离子引入量，约为30 μmol/g-聚合物，只需一步合成。利用亲水性聚合物如聚（环氧乙烷）（PEO）作为臂产生水溶性星星聚合物。在本研究中获得的含Eu（III）的PEO星星聚合物是水溶性的并且显示荧光。此外，它在水中1个月后稳定。该含Eu（III）的星星型聚合物在紫外光照射下具有较高的发光性能，在有机溶液中的量子产率为60%，在水溶液中的量子产率为19%.© 2013 Wiley Periodicals，Inc.

Water‐soluble luminescent material was developed by introducing europium (Eu(III)) ions into the core of a star polymer. Living radical polymerization was used to obtain the star polymer. The strategy to introduce Eu(III) ions into the star polymer was studied using poly(methyl methacrylate) as an arm. The best Eu(III) ion introduction was obtained by simultaneous introduction, resulting in about 30 µmol/g‐polymer, which needed only one step for synthesis. The utilization of a hydrophilic polymer such as poly(ethylene oxide) (PEO) as an arm produced a water‐soluble star polymer. The Eu(III)‐bearing PEO star polymer obtained in this study was water soluble and showed fluorescence. In addition, it was stable in water after 1 month. The Eu(III)‐bearing star polymer exhibited luminescent properties under UV light irradiation with relatively high quantum yields of 60% in organic solution and 19% in aqueous solution. © 2013 Wiley Periodicals, Inc.
