Hydrogen Bond-Induced Rigid Oligoanthranilamide Ribbons That Are Planar and Straight

A new series of oligoanthranilamides has been synthesized starting from suitably modified p-phenylenediamine and p-phthalic acid derivatives.
Due to strong intramolecular three-center hydrogen bonds, the new oligomers self-assemble into highly stable straight and planar molecular
ribbons, which have been characterized by X-ray crystallography and 1H NMR, IR, and UV−vis spectroscopy.

本研究以经适当修饰的对苯二胺（p-phenylenediamine）与对苯二甲酸（p-phthalic acid）衍生物为起始原料，合成了一系列新型寡聚邻氨基苯甲酰胺（oligoanthranilamides）。由于存在强分子内三中心氢键，这类新型寡聚物可自组装形成高度稳定的直链平面分子带状结构，该结构已通过X射线晶体学、核磁共振氢谱（1H NMR）、红外光谱（IR）以及紫外-可见光谱（UV−vis）完成表征。
