Utilization of 2,6-bis(2-benzimidazolyl)pyridine to detect toxic benzene metabolites

The tridentate ligand 2,6-bis(2-benzimidazolyl)pyridine has the ability to detect toxic benzene metabolites such as phenol, hydroquinone, resorcinol, catechol and p-benzoquinone by simple techniques like UV/vis and fluorescence spectroscopy. The formation of a stable supramolecular complex between 2,6-bis(2-benzimidazolyl)pyridine and hydroquinone was confirmed by X-ray analysis.

Graphical abstractIt is demonstrated that 2,6-bis(2-benzimidazolyl)pyridine can act as a sensor to detect toxic metabolites of benzene such as phenol, hydroquinone, resorcinol, catechol and p-benzoquinone.Figure optionsDownload full-size imageDownload as PowerPoint slide
