A series of novel ternary organic-inorganic mesoporous polymeric hybrids TTFA-S16-Eu-PMMA, TTFA-S16-Eu-PMAA, and TTFA-S16-Eu-PVP (TTFA = 2-Thenoyltrifluoroacetone; PMMA = polymethyl methacrylate; PMAA = polymethacrylic acid; PVP = polyvinylpyrrolidone) have been assembled by the Eu(3+) complex covalently attaching to the TTFA directly functionalized ordered mesoporous SBA-16 and organic polymer. FTIR, UV, XRD, TEM, N(2) adsorption measurements, photoluminescent spectra, and TG plots were characterized, and the results reveal that they all have high surface area, uniformity in the mesostructure, and good crystallinity. In addition, the ternary rare earth mesoporous polymeric hybrids show an overall increase in luminescent lifetime and quantum efficiency compared to binary rare earth mesoporous hybrid TTFA-S16-Eu, especially the mesoporous hybrid with PVP exhibits the highest luminescence quantum efficiency and longest lifetime.
一系列新型的三元有机-无机介孔聚合物杂化材料 TTFA-S16-Eu-PMMA、TTFA-S16-Eu-PMAA 和 TTFA-S16-Eu-PVP（TTFA = 2- 三氟乙酰丙酮；PMMA = 聚甲基丙烯酸甲酯；PMAA = 聚甲基丙烯酸；PVP = 聚乙烯吡咯烷酮）已通过将 Eu（3+）配合物共价连接到 TTFA 直接功能化的有序介孔 SBA-16 和有机聚合物上组装而成。对其进行了 FTIR、UV、XRD、TEM、N2 吸附测量、荧光光谱和 TG 图谱的表征，结果表明它们均具有高比表面积、介孔结构的均一性和良好的结晶度。此外，三元稀土介孔聚合物杂化材料与二元稀土介孔杂化 TTFA-S16-Eu 相比，其荧光寿命和量子效率均有整体提高，特别是具有 PVP 的介孔杂化材料表现出最高的荧光量子效率和最长的寿命。
