  Photofunctional Eu3+/Tb3+ hybrids through sulfoxide linkages: coordination bonds construction, characterization and luminescence

  摘要：

  采用溶胶-凝胶方法获得了新型有机-无机杂化材料，由稀土（Eu3+, Tb3+）络合物与硅基网络共价结合而成。通过亚甲基改性反应合成了三种新型多功能分子建筑块，含有亚磺酰基有机单元，作为稀土离子的配体，同时也作为硅氧烷网络的前体。所获得的杂化材料通过化学分析及FTIR、UV等光谱方法进行表征，并采用XRD和SEM。对制备的杂化材料进行了光致发光测量，显示出在可见光（Eu3+, Tb3+）区域的4fn内发射，且在所有情况下均被亚磺酰基配体所敏化。同时，详细研究了Eu3+杂化材料的发射量子效率和Judd–Ofelt强度参数。

  A novel polysilsesquioxane bridge (PPSSi) is synthesized with methylene group modification of phenylphenacyl sulfoxide by isocyanate group from 3-(triethoxysilyl)propyl isocyanate (TEPIC). Then ternary lanthanide (Eu, Tb) hybrids of polysilsesquioxane bridge (PPSSi) and four kinds of polymer chain (polyacrylamide (PAM), polyvinylpyrrolidone (PVP), polymethyl methacrylate (PMMA) and polyethyl methacrylate (PEMA) were assembled wth coordination bonding. To explore the influence of the different polymeric chains on the properties of lanthanide hybrids, the microstructure and photoluminescent properties of these lanthanide coordination polymer hybrids (PPSSi-Ln-PAM (PVP, PMMA, PEMA)) are compared in detail. Four organic polymer chains with different structures not only can coordinate to the lanthanide ions by their own carbonyl groups, but also can form a polymeric matrix together with the inorganic Si–O network. The results show that all the obtained hybrids could show efficient intramolecular energy transfer and lead to excellent characteristic emission of lanthanide ions. Moreover, the different structures of the polymers induce different microstructures and different photoluminescent behavior (lifetime and quantum efficiency) for these hybrid systems. The PPSSi-Ln-PMMA hybrid leads to the longest lifetime and highest quantum efficiency.

  通过 3-(三乙氧基甲硅烷基)丙基异氰酸酯 (TEPIC) 的异氰酸酯基团对苯甲酰亚砜进行亚甲基修饰，合成了一种新型聚倍半硅氧烷桥 (PPSSi)。然后将聚倍半硅氧烷桥（PPSSi）与四种聚合物链（聚丙烯酰胺（PAM）、聚乙烯吡咯烷酮（PVP）、聚甲基丙烯酸甲酯（PMMA）和聚甲基丙烯酸乙酯（PEMA））通过配位键合组装成三元镧系元素（Eu，Tb）杂化物。探讨了不同聚合物链对稀土杂化物性能的影响，详细比较了这些稀土配位聚合物杂化物（PPSSi-Ln-PAM（PVP、PMMA、PEMA））的微观结构和光致发光性能。不同结构不仅可以通过自身的羰基与镧系离子配位，而且可以与无机Si-O网络一起形成聚合物基体。结果表明，所有获得的杂化物都可以表现出有效的分子内能量转移并产生优异的分子内能量传递。此外，聚合物的不同结构导致这些混合系统具有不同的微观结构和不同的光致发光行为（寿命和量子效率）。 PPSSi-Ln-PMMA 混合材料具有最长的寿命和最高的量子效率。

  New kinds of organic–inorganic hybrid materials consisting of rare earth (Eu3+, Tb3+) complexes covalently bonded to a silica-based network have been obtained by a sol–gel approach. Three novel versatile molecular building blocks containing sulfoxide organic units have been synthesized by methylene modification reaction, which are used as the ligands of rare earth ions and also as siloxane network precursors. The obtained hybrids are characterized by chemical analysis and spectroscopic methods such as FTIR and UV; XRD and SEM. Photoluminescence measurements on the prepared hybrids were performed showing the intra-4fn emission in the visible (Eu3+, Tb3+) region and in all the cases being sensitized by the sulfoxide ligands. The emission quantum efficiency and the Judd–Ofelt intensity parameters of Eu3+ hybrid materials were also investigated in detail.
