Abstract
Benzimidazole based derivate [2-(4,7-di(thiophen-2-yl)-1H-benzo[d]imidazol-2-yl)-6-hydroxymethyl)-4-methylphenol (BI) modified reduced graphene oxide (BI-RGO) was prepared by simple non-covalent functionalization. Analytical spectroscopy by (Fourier transform infrared, UV-Visible and Raman) revealed the modification has occurred by RGO with BI through $\pi$–$\pi$ interaction. The Photoluminescence spectrum shows that BIRGO has 18% quenching compared to neat BI derivatives. UV-Visible and PL Spectrum reveals the electronic and optical properties of the BI and the changes that occurs after functionalization. Raman and FTIR spectrum of the compounds also revealed the presence of different functional groups and structural configuration. RGO and RGO-BI which provides all the details for further study regarding sensor applications.
