DENDRIMERS, ARBOROLS, AND CASCADE MOLECULES - BREAKTHROUGH INTO GENERATIONS OF NEW MATERIALS

Compounds with extremely(~)(for example 1) that are formed in iterative syntheses are penetrating many disciplines of chemistry. Compound 1 has 36 carboxyl groups on its periphery and can be considered a unimolecular micelle. Recently dendrimers have found their way into coordination chemistry through a compound which contains up to 22 metal centers per molecule (see also Balzani et al. Angew. Chem. Int. Ed. Engl. 1942, 31, 1493).(~)[GRAPHICS]
