A hybrid polymer of SiO@Tb(poly(ethylene terephthalate)-tetraglycol) phenanthroline (SiO@Tb(PET-TEG)Phen) was synthesized by mixing of inorganic SiO nanoparticles with polymeric segments of PET-TEG, whereas PET-TEG was achieved through multi-step functionalization strategy. Tb ions and β-diketonate ligand Phen were added in resulting material. The experimental results demonstrated that it was well blended with PET as a robust additive, and not only promoted the crystallinity, but also possessed excellent luminescence properties. An investigation of the mechanism revealed that the SiO nanoparticles functioned as a crystallization promotor; the Tb acted as the fluorescent centre; and the PET-TEG segments played the role of linker and buffer, providing better compatibility of PET matrix with the inorganic component. This work demonstrated that hybrid polymers are appealing as multifunctional additives in the polymer processing and polymer luminescence field.
通过将无机SiO纳米颗粒与聚对苯二甲酸乙二酯-四甘醇（PET-TEG）的聚合物链段混合，合成了一种SiO@Tb（聚对苯二甲酸乙二酯-四甘醇）菲咯啉杂化聚合物（SiO@Tb(PET-TEG)Phen），而PET-TEG是通过多步功能化策略实现的。将Tb离子和β-二酮配体菲咯啉添加到所得材料中。实验结果表明，它作为一种强大的添加剂与PET很好地混合，不仅提高了结晶度，还具有优异的发光性能。对其机理的研究表明，SiO纳米颗粒起到结晶促进剂的作用；Tb作为荧光中心；PET-TEG链段起到连接体和缓冲剂的作用，使PET基体与无机组分具有更好的相容性。这项工作表明，杂化聚合物作为聚合物加工和聚合物发光领域的多功能添加剂具有吸引力。
