A macrogelator based on azobenzene (Azo) and three biphenyl derivatives (3BP) with 1,4-phenylenediformamide core was designed for wringing gel. In bulk state, Azo-3BP was formed layered superstructure driven by the intermolecular hydrogen bonds and spacing-filling. But the Azo-3BP formed a three-dimensional (3D) network organogel in solution. The 3D organogel was compressed by UV light and the 3D network was transformed into layered morphology. It was driven by photoisomerization of azobezene moiety. The metastable 3D network of Azo-3BP was mainly by phase separation in solution. The light responsive wringing gels can be applicable to remote-controllable sensor, and delivery system.
