含Schiff base结构新型噻吩基偶极功能分子的制备

Preparation of Novel Dipolar Thiophene Chromophores Containing Schiff Base Structure

以噻吩为原料,经N-溴代丁二酰亚胺溴代、硝化、还原后得到3-氨基-2,5-二溴噻吩,再与含不同官能团的水杨醛类化合物发生缩合反应,得到3种含Schiff base结构新型噻吩基功能化合物,并采用IR、1H NMR等技术对化合物结构进行了表征。此类化合物分子结构中具有不同偶极功能基团,有利于分子聚合,是制备含噻吩基有机光电聚合物材料的重要前体。

Three novel dipolar thiophene chromophores with Schiff base structure were synthesized via bromination,nitration,reduction and condensation reactions. The structures of these compounds were confirmed by FT-IR and1H NMR. All these chromophores have further polymerizable groups at one end of the molecules. These compounds can be used as the potential precursors to prepare the highly active photoelectric polymeric materials.
