Versatile supramolecular organogel with outstanding stability toward aqueous interfaces

In this communication, we report on a novel and versatile low-molecular-weight organogelator. The methanolic gel exhibits an exceptional water-enhanced stability as evidenced by a 30°C increase in Tg with up to 10%v/v of water. This atypical property not observed with other solvents makes of this su...
