合成了(丙烯酸)二(α-噻吩甲酰三氟丙酮)钐[Sm(TTA)_2AA)]配合物,并通过本体聚合合成了Poly(MMA-co-Sm(TTA)_2AA)光致发光材料,采用红外光谱分析、示差扫描量热法、荧光光谱分析等进行了表征。结果表明,Poly(MMA-co-Sm(TTA)_2AA)在391 nm和415 nm的波长激发下在560 nm、596 nm、642 nm处发射出Sm3+的4G5/2→6H5/2,4G5/2→6H7/2,4G5/2→6H9/2跃迁的特征荧光,其发光强度优于配合物Sm(TTA)_2AA。而其玻璃化温度T g与聚甲基丙烯酸甲酯(PMMA)相比有所提高。
Sm (TTA) _2AA] (bis (α-thienyltrifluoroacetonate)] complex was synthesized and the poly (MMA-co-Sm (TTA) _2AA) photoluminescent material was synthesized by bulk polymerization , Characterized by infrared spectroscopy, differential scanning calorimetry, fluorescence spectroscopy and so on. The results showed that Sm5 + 4G5 / 2 → 6H5 / 2, 4G5 / 2 were emitted at 560 nm, 596 nm and 642 nm under the excitation of 391 nm and 415 nm by Poly (MMA-co-Sm (TTA) → 6H7 / 2, 4G5 / 2 → 6H9 / 2. The luminescence intensity of the characteristic fluorescence is better than that of the complex Sm (TTA) _2AA. The glass transition temperature T g is increased compared to polymethylmethacrylate (PMMA).
