    • Equilibrium constants and protonation site for N-methylbenzenesulfonamides 

      Moreira, José A.; Costa, Ana M. Rosa da; García Río, Luis; Pessêgo, Márcia Isabel Duarte (Beilstein Institute, 2011)
      The protonation equilibria of four substituted N-methylbenzenesulfonamides, X-MBS: X = 4-MeO (3a), 4-Me (3b), 4-Cl (3c) and 4-NO2 (3d), in aqueous sulfuric acid were studied at 25 °C by UV–vis spectroscopy. As expected, ...
    • Novel Supramolecular Nanoparticles Derived From Cucurbit[7]uril and Zwitterionic Surfactants 

      Fernández Rosas, Josefa; Pessêgo, Márcia Isabel Duarte; Acuña, Angel; Vazquez-Vazquez, Carlos; Montenegro García, Javier; Parajo, Mercedes; Rodriguez-Dafonte, Pedro; Nome, Faruk; García Río, Luis (American Chemistry Society, 2018-02-12)
      Binding constants, Log K ≈ 6.6 M-1, and NMR characterization of the complexes formed by sulfobetaines and cucurbit[7]uril (CB7) support the electrostatic interaction as major driving force. This very strong binding motif ...
