摘要
合成了 3种新型偶氮染料 :2 ( 4 甲基 2 噻唑基偶氮 ) 5 (二乙胺基 )苯酚 (MTADP)及其镍螯合物 (Ni MTADP)和锌螯合物 (Zn MTADP)。采用元素分析、MS、FT IR和FT Raman技术进行了结构表征。紫外 /可见吸收光谱分析表明 ,金属离子与MTADP形成螯合物后 ,在薄膜中最大吸收峰红移 60～ 70nm ,而且Ni MTADP比Zn MTADP有 1 0nm的红移。TG分析表明 ,Ni MTADP和Zn MTADP的分解温度分别为 3 3 1和 2 95℃。
Three novel azo dyes, (2-(4-methyl-2-thiazolylazo)-5-diethylaminophenol,MTADP) and its nickel and zinc chelates have been synthesized. The structures of the compounds are characterized by elemental analysis, MS, FT-IR and FT-Raman spectroscopy. The UV-Vis absorption spectra indicated metal chelation results in about 60～70 nm bathochromic shift of absorption band. Bathochromic shift of Ni-MBADP is about 10 nm larger than that of Zn-MBADP. The decomposition temperature peak is observed at 331 ℃ for Ni-MTADP and 295 ℃ for Zn-MTADP by thermo-gravimetric analysis, respectively.
