| Abstract: | A linear molecular architecture equipped with complementary three‐fold hydrogen‐bonding units embedded with a photoswitchable trans ‐tetrafluoroazobenzene moiety was synthesized. The trans to cis photoisomerism of the azobenzene unit induced drastic changes in the molecular architecture as a result of intramolecular hydrogen bonding as evidenced by NMR spectroscopy and size exclusion chromatography. A minute stereogenic element in the linear trans state enabled stereoselective folding into the cis state, thus producing a globular architecture with enhanced chiroptical property. |
