"The aims of the project have been accomplished. The combination of calixarene moieties within dendritic structures leads to novel supramolecular systems acting as receptors towards both anions and cations.

"The overall shape of hyperbranched polymer (dendritic structures) could be controlled by using of appropriate multivalent core. The geometry of this core determines the direction of branching while the number of its functional groups keeps control overthe number of branches. The chemistry of calix[n]arenes offers us a broad variations in the structural and geometrical features of calixarene derivatives, what makes the calixarenes the ideal candidates for the core moieties of dendrimers. Usingcalix[4]arenes immobilised in appropriate conformations (cone, partial cone, 1,3-alternate) will lead to the structures with different overall geometry and hence to the materials possessing different physico-chemical properties. On the other hand, theincorporation of calix[n]arene moieties into the surface of dendritic structures can yield compounds possessing extraordinary properties, e.g. high complexation ability towards charged or even neutral molecules.
