Синтезирован и исследован лиганд (L) N,N′-бис(2-гидроксибензил)-1,2-диаминоэтан. С помощью спектрофлуориметрии и спектроскопии в ультрафиолетовом и видимом диапазонах изучена чувствительность L к ионам различных металлов. Сенсор на основе L обнаруживает высокую чувствительность в отношении ионов Fe3+ и Fe2+ в ацетонитриле. Тушение флуоресценции L обусловлено главным образом ионами Fe3+ , а ее значительное усиление наблюдается в присутствии ионов Zn2+ . С помощью многофакторного моделирования рассчитаны стехиометрия, концентрация и спектральные профили, а также константы образования изучаемых комплексов.

A new ligand (L), N,N′-bis(2-hydroxybenzyl)-1,2-diaminoethane, was synthesized and characterized. The sensing behavior of L toward various metal ions was investigated by spectrofluorometric and UV-Vis spectrophotometric methods. The sensor displayed selective and sensitive recognition toward Fe3+ and Fe2+ in acetonitrile. The fluorescence of L was quenched mainly by Fe3+ , and a considerable enhancement of fluorescence was observed in the presence of Zn2+ . Using multivariate hard modeling and stoichiometry, the concentration, spectral profiles, and formation constants of the studied complexes were calculated.
