Light-driven nanofiber and nanoring morphological transformations in organogels based on an azobenzene-bridged biscalix[4]arene†
Abstract
The morphologies of an azobenzene-bridged biscalix[4]arene organogel in different organic solvents can be photo-reversibly switched between nanofibers and nanorings as well as between closed and open-form vesicles.
