An extraordinary cylinder-to-cylinder transition in the aqueous assemblies of fluorescently labeled rod-coil amphiphiles.
We report an unprecedented cylinder-to-cylinder transformation in the self-assemblies of pyrene-labeled rod-coil molecules in water. The extraordinary morphological transformation can be monitored by a fluorescence variation from exciplex to excimer emissions, suggesting the rod-packing transition from antiparallel to interdigitated arrangements as a function of PEO coil length.
