Host-Guest Compounds Oligomeric Cucurbituril Complexes: from Peculiar Assemblies to Emerging Applications
Résumé
Proteins are an endless source of inspiration. By carefully tuning the
amino-acid sequence of proteins, nature made them evolve from
primary to quaternary structures, a property specific to protein oligomers and often crucial to accomplish their function. On the other
hand, the synthetic macrocycles cucurbiturils (CBs) have shown
outstanding recognition properties in water, and a growing number of
(host)n:(guest)n supramolecular polymers involving CBs have been
reported. However, the burgeoning field of discrete (n:n) host:guest
oligomers has just started to attract attention. While 2:2 complexes are
the major oligomers, 3:3 and up to 6:6 oligomers have been described,
some associated with emerging applications, specific to the (n:n)
arrangements. Design rules to target (n:n) host:guest oligomers are
proposed toward new advanced host:guest systems.
