NMR confirms molecular switches retain function in
2-D-array

Researchers led by Jiří Kaleta of IOCB Prague have
synthesized regular 2-D assemblies of isotopically labelled
molecular switches and measured the properties of their
isomerization, revealing that formation of such an assembly doesn’t
hamper the photochemical switching properties of the embedded
molecules. The isotopic labels came into use when measuring
switching properties using an analytic technique dependent on the
labels. The team published the results in the Journal of the
American Chemical Society.
