Di-urea compounds as gelators for organic solvents

Article abstract of DOI:10.1016/S0040-4039(96)02292-7

Simple diurea compounds form thermoreversible gels with several organic solvents. These gels are stable up to temperatures of 100°C, and can be stored for months. Electron microscopy reveals that in these solvents the gelation agents assemble into very thin rectangular sheets which are several tens of micrometers long.
