Some racemates (Figure 3.23) are more efficiently resolved on the bonded-type CSP than the coated-type CSP by using chloroform as a component of the eluent. On the bonded-type CSP of 24n, topologically interesting catenanes and molecular knots are successfully resolved using a hexane-chloroform-2-propanol mixture.185 The first direct HPLC resolution of the smallest chiral...

Since the pioneering work of Charles J. Pedersen, Donald J. Cram and Jean-Marie Lehn, macrocyclic chemistry attracted a considerable attention from chemists all over the world [1-4]. An ability of macrocycles to be highly selective receptors (host molecules) for a number of metal and organic cations or anions, as well as for the small or even huge (e.g. fiillerenes) neutral organic substances is the reason of that interest [5-8]. The design of molecular devices such as molecular containers and reactors on one hand, and molecular switches (based on catenanes and molecular knots) on the other hand is another area of the macrocyclic chemistry application. So, the macrocyclic chemistry plays an important role in the material science, especially in the constmction of nano-sized materials on the bottom-up principles [5, 6, 9-11].
