A structural and 1H NMR relaxometric study on novel layered carboxyalkylaminophosphonate nanocrystals with Gd(iii) ions located in the framework†
Abstract
Novel Gd(III) carboxyalkylphosphonate nanocrystals were synthesized under mild hydrothermal conditions. Structural properties and 1H NMR relaxometric behaviour in aqueous solution as a function of the magnetic field strength were investigated, aiming to evaluate the local chemical environment of the paramagnetic centres and their interaction and affinity with water molecules.
