Reversible heterochiral aggregation/dissociation of bis(2-hydroxyphenyl) diamides driven by UV/Vis irradiation

Nojiri, Akihiro,Kumagai, Naoya,Shibasaki, Masakatsu

, p. 2137 - 2141 (2012/04/10)

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
