Exchange Speed of Four-Component Nanorotors Correlates with Hammett Substituent Constants
Three distinct four-component supramolecular nanorotors were prepared, using, for the first time, bipyridine instead of phenanthroline stations in the stator. Following our established self-sorting protocol to multicomponent nanodevices, the nanorotors were self-assembled by mixing the stator, rotators with various pyridine head groups, copper(I) ions and 1,4-diazabicyclo[2.2.2]octane (DABCO). Whereas the exchange of a phenanthroline vs. a bipyridine station did not entail significant changesdoi:10.3390/chemistry3010009 fatcat:dafbmguwpbgp5cuaylfftpepii
