Theory of Solvation-Controlled Reactions in Stimuli-Responsive Nanoreactors [PDF]

, 2015
Metallic nanoparticles embedded in stimuli-responsive polymers can be regarded as nanoreactors since their catalytic activity can be changed within wide limits: the physicochemical properties of the polymer network can be tuned and switched by external ...

Der Einfluß der Donorzahl des Lösungsmittels auf chemische und elektrochemische Vorgänge

CHIMIA, 1969
Complex formation in donor solvents is favoured by decreasing donor number of the solvent molecules and by increasing donor number of the ligand to be coordinated. The solvation of metal ions is discussed for both hard and soft ions.
