2,6-Bis(2-benzimidazolyl)pyridine, bbp, a simple tridentate ligand, is employed as a receptor for the recognition of anions. The binding of anionic guest species with bbp can be studied in short duration using UV/vis spectroscopy, fluorescence spectroscopy and (1)H NMR techniques at very low concentrations. The results obtained from the above spectroscopic techniques indicate that 2,6-bis(2-benzimidazolyl)pyridine is an efficient anion receptor providing chemical shift and optical modification based signals for the detection of acetate ions.
2,6-双(苯并咪唑基)吡啶（bbp）是一种简单的三齿配体，可作为阴离子识别的受体。使用紫外/可见光谱、荧光光谱和（1）H NMR 技术，可以在非常低的浓度下在短时间内研究阴离子客体与 bbp 的结合。上述光谱技术的结果表明，2,6-双(苯并咪唑基)吡啶是一种有效的阴离子受体，为检测乙酸根离子提供了基于化学位移和光学修饰的信号。
