Abstract / Bemerkung

Visible light can be used to shift dynamic covalent imine assemblies out of equilibrium. We studied a fluorinated azobenzene building block that reliably undergoes geometric isomerism upon irradiation. The building block was used in combination with two different amines, ethylenediamine and R,R-1,2-diaminocyclohexane, to create a library of imine macrocycles. Whereas the simple amine can be used to access a polymeric state and a defined bowl-shaped macrocycle, the chiral amine gives access to a rich network of macrocycles that both undergo isomerisation as well as interconversion between different macrocyclic species, allowing for control of the number of monomers involved in cyclo-oligomerization, which were investigated using 1H- and 19F-DOSY NMR, MALDI-MS measurements, and UV/VIS spectroscopy. © 2022 Wiley-VCH GmbH.
