Abstract

Invited for the cover of this issue are the group of Iwona and Jean-François Nierengarten from the University of Strasbourg (LIMA, UMR 7042, CNRS) and collaborators from the University of Carthage. The image depicts a sky of umbrellas floating in the air to illustrate the protective effect allowing the efficient mono-acylation of a symmetrical rotaxane building block with two pentafluorophenyl ester stoppers.
