| 摘要: 本文报道了一种新的配体:10-乙基-3-甲酰吩噻嗪缩肼基二硫代甲酸甲酯(HL)及其金属配合物的合成。采用了元素分析、质谱、核磁共振、红外光谱对配体及其金属配合物进行了表征。此外,并应用紫外、荧光和Z-扫描技术,测定了配体及其金属配合物的荧光最佳发射波长(λmaxem)、荧光量子产率(Φf)、寿命(τ)和非线性光学性质。结果表明它们在DMF溶液中都能发射出较强的橄榄色荧光,配体及其金属配合物都有双光子吸收,并且金属配合物的非线性光学效应比配体明显增强。用半经验量子化学方法(RHF/PM3)计算结果与实验值较为吻合。 |

| Abstract: A new ligand, S-methyl-β-N-[10-ethylphenothiazine-3-methylene] dithiocarbazate (abbreviated as HL) and its complexes ML2(M=Ni,Cu,Zn,Cd and Pd) have been synthesized and characterized by elemental analyses, EI-MS, 1H NMR, IR, UV-vis spectra, photoluminescence measurements. All of the compounds emit an olivine color in DMF solution. The emission maxima (λmaxem), fluorescence quantums (Φf), and lifetimes (τ) of each compound are measured. The nonlinear absorptions of HL and ML2 solutions (in DMF) are measured by open-aperture Z-scan technique at a 532nm wavelength. Theoretical calculations were consistent with the experi-mental results. |
