Langmuir films of 2-alkyl benzimidazoles on aqueous AgNO3 subphase and the layer structures of the transferred films was written by Wu, Yi-Tian;Liu, Ming-Hua. And the article was included in Wuli Huaxue Xuebao in 2004.Formula: C15H22N2 This article mentions the following:
The formation of stable Langmuir films on the aqueous AgNO3 subphase of 2-alkyl benzimidazoles(BzCn) with various chain lengths (from C5 to C15) and the layer structures of the transferred films were described. From the surface pressure-area isotherm, the true monolayer could be formed for the short chain derivatives, while multilayer structures for the long ones. All of the Langmuir films could be transferred to solid substrate. The measurement of the UV spectra of the transferred LB films confirmed the coordination between benzimidazole group and Ag(I) ion in the Langmuir films. The effect of the length of alkyl chains on the structure of the transferred LB films was revealed by application of at. force microscopy, FF-IR spectra and XRD measurement. Except for BzC15, a regular layer structure was formed. Characterization of the morphol. points to the formation of the neat LB film for the short derivatives and multilayer structure for BzC15. In the experiment, the researchers used many compounds, for example, 2-Octylbenzimidazole (cas: 13060-24-7Formula: C15H22N2).
2-Octylbenzimidazole (cas: 13060-24-7) belongs to imidazole derivatives. Imidazole is a heterocyclic compound with a five-membered planar ring. It is amphoteric and highly polar. The pharmacophore of imidazole exists in bioactive compounds including amino acids, plant growth regulators and therapeutic agents.n increase of the alkyl chain length of the alcohols. Formula: C15H22N2
