【摘要】 利用3,5-二氨基苯甲酸和4,6-二羟基间苯二酸的衍生物设计并合成了一类新芳香酰胺聚合物.其溶解度、浓度核磁、紫外可见吸收光谱(UV)和圆二色谱(CD)实验表明,聚合物可以发生折叠形成螺旋结构,折叠聚合物的侧链酰胺间的分子内氢键作用可以稳定螺旋构像.更多还原

【Abstract】 Long aromatic polymer chains which based on 3,5-diaminobenzoic acid derivatives and 4,6-dihydroxyisophthalic acid derivatives are designed and synthesized. The results of solubility, NMR, UV-Vis spectrum and circular dichroism(CD)experments indicate that the polymer adopts a hollow helical conformation that is stablized by intramolecular H-bonding interaction between side chains.更多还原
