Abstract: | With unique three-dimensional triptycene derivatives as the building blocks, several kinds of novel macrocyclic compounds including triptycene-derived calixarenes, heterocalixarenes, N(H)-bridged azacalixarenes, homooxacalixarene analogues, and tetralactam macrocycles could be conveniently synthesized with satisfactory yields by one-pot method or two-step fragment coupling reactions. With rigid triptycene moiety, these macrocyclic hosts not only have large enough cavities, but also show specific fixed conformations. These structural features made them exhibit well molecular recognition toward small organic molecules, fullerenes and organic dyes. Moreover, these macrocycles could also show interest self-assembly abilities in both solution and solid state, which will make them be broad application prospects. |
