Résumé
Two generations of lipophilic pyrenyl functionalized poly(benzyl ether) dendrimers (P1 and P2) have been synthesized. The thermal properties of the two functionalized dendrimers have been investigated, and the pyrenyl group of the dendritic mols. encapsulated in the arene-ruthenium metalla-cage, [Ru6(p-cymene)6(tpt)2(donq)3]6+ ([1]6+) (tpt=2,4,6-tri(pyridin-4-yl)-1,3,5-triazine; donq=5,8-dioxydo-1,4-naphthoquinonato). The host-guest properties of [P1?1]6+ and [P2?1]6+ were studied in soln. by NMR and UV/Vis spectroscopic methods, thus allowing the detn. of the affinity consts. Moreover, the cytotoxicity of these water-sol. host-guest systems was evaluated on human ovarian cancer cells. [on SciFinder(R)]
