Donor-acceptor molecular figures-of-eight

摘要

The intermolecular template-directed synthesis, separation and characterisation of two constitutional isomers that are selfcomplexing donor-acceptor [1]rotaxanes has been achieved by click chemistry, starting from a π-electron deficient tetracationic cyclophane containing two azide functions and a re-electron rich 1,5-dioxy naphthalene-containing poly ether chain terminated by propargyl groups.
