Abstract

Abstract : An octacationic tetraviologen-based cyclophane—so calledTVBox 8+ —can form a ring-in-ring complex with bis-1, 5-dinaphtho[50]crown-14, which represents a key intermediate for constructing molecular Borromean rings in a stepwise manner. Abstract : A rigid octacationic tetraviologen-based cyclophane, TVBox 8+, is reported. It possesses a highly electron-deficient rectangular cavity with a length of 23 Å and width of 6.1 Å and is capable of encapsulating either two small π-aromatic guest molecules, such as PhMe and PhCl, simultaneously, or one large molecule, e.g., bis-1, 5-dinaphtho[50]crown-14.
