Abstract

Interpenetrated molecules have attracted increasing attention from chemists not only because of their intriguing architectures and topologies, but also as a result of potential applications in molecular machinery and nanotechnology. In this account we review recent efforts on the construction of interpenetrated molecules based on the molecular recognition toward some positively charged axle components in aqueous or organic medium. We mainly focus on guest molecules containing ammonium, anilinium, and pyridinium groups. The host molecules are cucurbiturils and crown ethers.
