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 <i>T</i>_g with up to 10%v/v of water. This atypical property not observed with other solvents makes of this supramolecular gel a highly stable matrix compatible with aqueous interfaces. As a proof of principle we present the sensing performance of a symmetric tricarbocyanine fluorophore bearing a Zn­(II)­chelator unit. The system retained its remarkable physical integrity for a long period of time opening new possibilities for other organic–aqueous interface applications
