Water-soluble polymer particles (PPs) with strong fluorescence emission were prepared from hyperbranched poly(ethylenimine) (PEI) and terpyridine-bearing aldehyde (TPy) Schiff base reaction and self-assembly in aqueous phase. TPy/PEI PPs were then used to develop a series of luminescent lanthanide coordination polymers particles (Ln-CPPs). The optical properties of these Ln-CPPs are readily modulated over a wide spectrum in water systems. Finally, water-soluble white-emitting Ln-CPPs were achieved by controlling the lanthanide ion stoichiometry. This Ln-CPPs design approach offers a robust pathway for white-luminescent materials in water systems.
通过超支化聚乙烯亚胺（PEI）与含三联吡啶的醛（TPy）在水相中进行席夫碱反应和自组装，制备了具有强荧光发射的水溶性聚合物颗粒（PPs）。然后，将TPy/PEI PPs用于制备一系列发光镧系配位聚合物颗粒（Ln-CPPs）。这些Ln-CPPs的光学性质在水体系中很容易在宽光谱范围内进行调节。最后，通过控制镧系离子化学计量比，获得了水溶性发白光的Ln-CPPs。这种Ln-CPPs的设计方法为水体系中的白色发光材料提供了一条可靠的途径。
