Abstract

Unlike rotaxanes, which have attracted much attention as relevant materials in diverse research fields (eg, sensing,[1] drug delivery,[2] gelation,[3] fluid transportation [4]), catenanes have been less applicable as functional interlocked materials, possibly because of their synthetic complexity (ie, the requirement for efficient macrocyclization). For small-ring systems, the introduction of heteroatoms or gem-dialkyl groups [5] into alkyl chains can ...
