Description générale

2,6-Bis(2-benzimidazolyl)pyridine acts as tridentate nitrogen donor ligand and reacts with UO2Cl2·3THF to form complexes. It is reported as an efficient anion receptor providing chemical shift and optical modification based signals for the detection of acetate ions. 2,6-bis(2-benzimidazolyl)pyridine is a V-shaped ligand and its picrate Mn(II) complex has been prepared. 2,6-Bis(2-benzimidazolyl)pyridine is also reported as an optical sensor useful for the aniline recognition.

Application

2,6-Bis(2-benzimidazolyl)pyridine may be employed as a chemosensor for the detection of fluoride ions. It may be used as a sensor for the detection of toxic metabolites of benzene such as phenol, hydroquinone, resorcinol, catechol and p-benzoquinone.

In this paper, an optical sensor, 2,6-bis(2-benzimidazolyl)pyridine, is reported to be highly selective towards aniline. A unique spectral response of 2,6-bis(2-benzimidazolyl)pyridine towards aniline is found, and a linear relationship between the sensor's emission intensity and the aniline's concentration is observed
