Description
  • Důsledkem kovalentní vazby metanofullerénu se dvěma molekulami Beta-cyklodextrinu dochází ke významnému zvýšení rozpustnosti látek 1 a 2 ve vodním prostředí. Obě látky tvoří ve vodním prostředí agregáty, což doposud znemožnilo potvrdit interní komplexaci C60 s Beta-cyklodextrinem v těchto molekulách. Proto byly naměřeny hodnoty reversibilních redox potenciálů látek 1 a 2 pro přenos prvního elektronu v čistém rozpouštědle bez přídavku základního elektrolytu na Pt ultramikroelektrodě. Porovnáním redox potenciálů volného C60 s těmito hodnotami bylo potvrzeno, že přinejmenším molekuly neagregované v micelárních útvarech podléhají interní komplexaci. (cs)
  • Covalent attachment of methanofullerene and two beta-cyclodextrins in compounds 1 and 2 leads to a remarkable solubility in water. However, in aqueous medium both compounds form aggregates which prevented to confirm internal complexation of C60 and beta-cyclodextrin. Here we report reversible redox potentials of the first electron transfer for 1 and 2. Data in pure solvents without electrolyte were measured on Pt ultramicroelectrode. Comparison of redox potentials with free C60 indicates that at least 1 and 2 not involved in micelles are complexed.
