In this paper, we report the synthesis, characterization, crystal structure, and photophysical properties of a Eu(3+) complex of Eu(TTA)(3)Phen, where TTA=2-thenoyltrifluoroacetonate, and Phen=1,10-phenanthroline. Its elementary application for oxygen-sensing application is also investigated by doping it into a polymer matrix of polystyrene (PS). Experimental data suggest that the 3wt% doped Eu(TTA)(3)Phen nanofibrous membrane exhibits a high sensitivity of 3.4 towards oxygen with a good linear relationship of R(2)=0.996. In addition, the 3wt% doped Eu(TTA)(3)Phen nanofibrous membrane owns a quick response of 9s towards molecular oxygen, along with its excellent atmosphere insensitivity and photobleaching resistance. All these results suggest that both Eu(TTA)(3)Phen and Eu(TTA)(3)Phen/PS system are promising candidates for oxygen-sensing optical sensors.
本文报道了 Eu(TTA)(3)Phen（TTA=2-噻吩甲酰三氟丙酮，Phen=1,10-菲啰啉）Eu(3+) 配合物的合成、表征、晶体结构和光物理性质。还通过将其掺杂到聚苯乙烯（PS）聚合物基质中，研究了其在氧传感应用方面的基本应用。实验数据表明，掺杂 3wt%Eu(TTA)(3)Phen 的纳米纤维膜对氧气具有 3.4 的高灵敏度，并且具有良好的线性关系 R(2)=0.996。此外，掺杂 3wt%Eu(TTA)(3)Phen 的纳米纤维膜对分子氧具有 9s 的快速响应，同时具有优异的大气不敏感性和耐光漂白性。所有这些结果表明，Eu(TTA)(3)Phen 和 Eu(TTA)(3)Phen/PS 体系都是氧敏光学传感器的有前途的候选材料。
