Light to dissolve: (R)- and (S)-diamides bearing a hydrogen-bonding framework (red in picture) and a trans-azobenzene unit (blue) form an insoluble heterochiral aggregate, which can be dissolved by photoisomerization of the azobenzene unit to the cis conformation by UV irradiation (365-nm). The insoluble aggregate was formed again by subsequent irradiation with visible light (>422-nm). The precipitation and dissolution is manifestly reversible. Copyright
