Closed Aromatic Tubes—Capsularenes

Abstract: In this study, we describe a synthetic method for incorporating arenes into closed tubes that we name capsularenes. First, we prepared vase-shaped molecular baskets 4-7. The baskets comprise a benzene base fused to three bicycle[2.2.1]heptane rings that extend into phthalimide (4), naphthalimide ( 6), and anthraceneimide sides (7), each carrying a dimethoxyethane acetal group. In the presence of catalytic trifluoroacetic acid (TFA), the acetals at top of 4, 6 and 7 change into aliphatic aldehydes followed by t… Show more

“…[1][2][3] Tremendous efforts have been made to create artificial molecules to mimic biomolecules, structurally or functionally. Among them, cage molecules are known as important molecular recognition mimics and are widely applied across multiple disciplines, [11][12][13][14][15][16] such as molecular separation, [17][18][19] catalysis, [20][21][22] molecular transport, [23][24][25] biological applications, 26,27 gas adsorption, 28,29 stabilization of species, 30 crystallography, 31 molecular sieves, 32 optoelectronics, 33,34 etc. The properties of a cage largely depend on its confined cavity and settled recognition sites, i.e.…”
