Abstract

An unusually asymmetric [2] catenane has been prepared by interlocking a hybrid crown macrocycle (containing one polyether and one butadiyne linker) with a diimide-derived macrocycle itself constructed with a pair of rigid butadiyne links. This system of complementary building blocks and connectors has proved a versatile vehicle for demonstration of a number of templating effects. Synthesis of the hybrid crown monomer ...
