| Outline of Final Research Achievements |
Azobenzene derivatives bearing complementary triple hydrogen bonding units on both sides have been designed and synthesized. UV irradiation of trans-compounds induced photoisomerization to cis-compounds, whose structure was characterized by folded globular conformation owing to intramolecular hydrogen bonding interactions. The folded structure was evident by 2D-NMR and size-exclusion chromatography. Structure and length of the linker connecting the azobenzen and the hydrogen bonding units are determinants for successful folding and unfolding. Intriguingly, introduction of a stereogenic center on the linker rendered the folding process enantiosleective, leveraging chiroptical property of the phtoresponsive compounds.
