Bimolecular Interactions Between Graphene Oxide and a New Aza-BODIPY Derivative

Fluorescent dyes are optical devices which are commonly used in medical and technical applications. Graphene-oxide, on the other hand, is a unique structure in nanotechnology with its oxygen-containing functional groups, high solubility, optical, electronic and thermal properties. Here we report photophysical properties of a newly synthesized fluorescent aza-BODIPY dye and dye-graphene oxide (GO) composite in aqueous media. Quantum yields were determined in both ethanol and chloroform medias according to Perker-Rees equation. Also quenching mechanism was discussed in the light of Stern-Volmer parameters.
