Binding Interaction study of 5-(difluoromethoxy)-2-Mercapto-1HBenzimidazole along with BaTiO3 Nanoparticle

Binding interaction of 5-(difluoromethoxy)-2-mercapto-1H-benzimidazole (DMMB) with BaTiO3 nanoparticle was studied. BaTiO3 nanoparticle was prepared by sol-gel method and characterized by powder X-ray diffraction(XRD). DMMB was loaded on the surfaceof the nanoparticle by adsorption. The interaction of DMMB with BaTiO3 were confirmed by Scanning Electron Microscopy (SEM), Energy- Dispersive X-ray spectroscopy(EDX), Fourier Transform Infrared Spectroscopy (FT-IR), Brunauer-Emmett-Teller (BET), ultraviolet absorption spectroscopy and fluorescence. The results observed proved that the interaction of the DMMB with BaTiO3 occur due to the electron transfer between DMMB and BaTiO3 nanoparticle. DMMB adsorption strongly supports on the surface of BaTiO3 nanoparticle possibly owing to the azomethine nitrogen atom chemical affinity. To confirm the binding of BaTiO3 with DMMB, photo instinct electron transfer is used alongwith fluorescence quenching of DMMB.
