Description

Application

Benzimidazole was used as template compound in the preparation of molecularly imprinted polymer via electropolymerization and electrodeposition of pyrrole on a pencil graphite electrode. It was also used in the preparation of benzimidazolium surfactant, 1-hexadecyl-1H-benzimidazole.

Fine-Tuning the Activation Mode of an 1,3-Indandione-Based Ruthenium(II)-Cymene Half-Sandwich Complex by Variation of Its Leaving Group.

Stephan Mokesch et al.

Molecules (Basel, Switzerland), 24(13) (2019-06-30)

Fine-tuning of the properties of a recently reported 1,3-indandione-based organoruthenium complex is attempted to optimize the stability under physiological conditions. Previous work has shown its capacity of inhibiting topoisomerase IIα; however, fast aquation leads to undesired reactions and ligand cleavage

Benzimidazolium surfactants for modification of clays for use with styrenic polymers.

Excited-state intramolecular proton transfer and charge transfer in 2-(2'-hydroxyphenyl)benzimidazole crystals studied by polymorphs-selected electronic spectroscopy.

Hayato Konoshima et al.

Physical chemistry chemical physics : PCCP, 14(47), 16448-16457 (2012-11-08)

Crystal structures of polymorphs of 2-(2'-hydroxyphenyl)benzimidazole (HPBI), Forms α and β, are analyzed by X-ray crystallography. The fluorescence excitation (FE) and fluorescence spectra of the polymorphs are separately observed at temperatures 77-298 K. It has been found that the electronic
