摘　　要：以水杨醛与芳香胺经席夫碱缩合反应合成系列具有不同取代位置芳香间隔基的Bola型席夫碱化合物。通过核磁共振、元素分析等手段对化合物的结构进行表征。利用紫外光谱和红外光谱研究了目标产物的间隔基效应和酸致变色性能。研究数据表明,随间隔基取代位置的变化,席夫碱分子中的电子分布和共轭结构发生了明显的改变,导致其光谱性质表现出显著的差异。由于在溶液与浇铸膜中组装模式的不同,化合物的酸致变色的程度表现出明显的不同,在功能材料等领域具有广泛的应用价值。Some Bola-type Schiff base compounds with aromatic spacers were synthesized through Schiff base reaction using salicylaldehyde and aromatic amines as starting materials. The structures of these compounds were characterized by NMR and EA. The spacer effect and acidichromism properties of the Schiff bases were investigated by using UV-vis and FT-IR spectroscopy. The results showed that the spectra properties of the Schiff base derivatives had distinct characteristics with the change of substituent position in aromatic spacer, which induced the change of electron distribution and conjugated structure. Due to the different assembly modes between in bulk solution and at cast film, the degree of aeidiehromism showed great difference, which would have broad prospects for application in the field of functional materials.
