Abstract
Abstract
A naphthalene diimide dye with two side amine arm was prepared. Uv-Vis and fluorescence spectroscopic techniques studied its photophysical and solvatochromic characteristics in different solvents. Its fluorescence quenching mechanism has been carried out as a fluorescence probe model with graphene oxide as an efficient quencher. The results indicated that graphene plays an effective quencher against the naphthalene diimide molecule. The Stern-Volmer analysis results show a combination of two static and dynamic quenching mechanisms via an energy transfer process.
