Molecular recognition and assembly of cyclotriveratrylenes

Supramolecular chemistry has rapidly developed since 1960＇s. Lots of artificial receptors have been abroad studied including crown ether, cryptand, spherand, cyclodextrin, cyclophane, calixarene and cucurbituril. CTVs （cyclotriveratrylenes） are a kind of macrocylic host molecules prepared from veratrole or veratryl alcohol, CTVs possess the rigid shallow cavity with electron-rich aromatic rings and are suited for the inclusion of fullerenes and construction of cryptophanes. CTVs can be derived to chiral receptors or building blocks with C3 symmetry, which show novel ability in chiral molecular recognition and self-assembly. In recent years, CTVs have attracted much more interests in supramolecular chemistry and material sciences. This review focuses on recent developments of cyclotriveratrylenes and cryptophanes, especially the remarkable properties of molecular recognition and assembly based on their functionalized derivatives in solution as well as in the solid state. The applications of CTVs in the field of biosensor devices, fullerene separation, and liquid crystals have also been highlighted.
