Pillar[5]arene derivatives bearing peripheral porphyrin subunits have been efficiently prepared from a deca-azide pillar[5]arene building block (17) and ZnII -porphyrin derivatives bearing a terminal alkyne function (9 and 16). For the resulting deca-ZnII -porphyrin arrays (18 and 20), variable temperature NMR studies revealed an intramolecular complexation(More)
A pillar[5]arene-containing rotaxane building block bearing exchangeable stoppers has been prepared in multi-gram scale quantities with high yields from the reaction of 2,4-dinitrophenol (DNP) with the inclusion complex resulting from the association of dodecanedioyl chloride with 1,4-diethoxypillar[5]arene. Stopper exchange reactions have been achieved by(More)
A sophisticated photoactive molecular device has been prepared by combining recent concepts for the preparation of multifunctional nanomolecules (click chemistry on multifunctional scaffolds) with supramolecular chemistry (self-assembly to prepare rotaxanes). Specifically, a clickable [2]rotaxane scaffold incorporating a free-base porphyrin stopper has been(More)
