Here, we report a dual stimuli-responsive organogel which can stabilize graphene oxide (GO) in apolar solvents. The gelator 1-octadecyl-ureido-naphthalene (OUN) was synthesized, and it could form organogel in toluene and xylene. The resultant gels can respond to thermal and anion stimuli, bringing about fluorescent changes. Thin nanoribbons are entangled together to form three dimensional networks that can immobilize solvents in gel, providing large superficial area to interact with GO sheets. The addition of GO influences the gel properties, which are studied through rheological, fluorescent, and DSC measurements.
