                Syntheses
                and Characterization of New Hosts

We have an active research program geared to the preparation of novel redox active molecular receptors. We have recently reported on a series of new cavitand hosts with covalently attached viologen subunits.1 Last year, in collaboration with the group of Professor Sherman, University of British Columbia, we reported the first synthesis of pentameric, hexameric and heptameric cavitands,2 which may result in an interesting new class of large cavity hosts. Our efforts with cucurbit[7]uril have also been noted in the section on dendrimers.3 Our current activity emphasizes the development of all these areas.
