Abstract

Owing to the unique opto-electronic properties, pyrazoline derivatives are considered to be one of the most elegant member in heterocyclic family. In this work we have utilized a pyrazoline dye 3-naphthyl-1-phenyl-5-(4-amino phenyl)-2-pyrazoline (NPAP) for functionalizing graphene oxide (GO) through amide linkage, as the progress of graphene based materials are quicker than other comparable materials. All the employed characterization techniques support the bridging of –NH bond between the two segments. Moreover, the enhanced photophysical properties of the resulting hybrid (GO-NPAP) reflect an efficient charge delocalization, allowing an electronic interaction at the interface of GO and NPAP partners as they are electronically separated. Very simple, economic and an effective reagent for making GO fluorescent, it is expected that the pyrazoline functionalized GO will hold a prominent position in developing high-performance graphene based devices.
