These new compounds were fully characterised by the usual spectroscopic techniques, such as IR and NMR. The photophysical properties of the amino acids were evaluated by UV-Vis absorption and fluorescence spectroscopy in solvents of different character. Interaction studies with biologically and analytically important ions such as F-, OH-, Cu2+ and Fe3+, through spectrophotometric and spectrofluorimetric titrations were carried out to assess their potential as chemosensors.Fundação para a Ciência e a Tecnologia (FCT)MDPIUniversidade do MinhoEsteves, Cátia I.
