含噻吩基Schiff bases化合物制备及其光学性能研究

摘要

分别以噻吩和2，5-二溴噻吩为原料，经硝化、还原后得到3-氨基噻吩衍生物，再与含不同官能团水杨醛类化合物发生缩合反应，得到4种含Schiff base结构新型噻吩偶基功能化合物。用IR、1H NMR等方法对化合物结构进行了表征，利用其UV-Vis和荧光光谱对化合物光谱性能进行了对比研究，结果表明，这4种化合物具有良好的光学性能。%In our present work, we synthesized a series of thiophehe compounds containing Schiff bases struc-tures used thiophene, 2, 5-dibromo thiophene as raw material, respectively. The construction of these compounds was haracterized by IR and 1H NMR spectroscopy. Then the ultraviolet-visible absorption spectrum and fluores-cence spectrum has been used to study the optical properties of these compounds. The results indicated that all of the compounds have the well optical properties.
