Synthesis, characterization and ion sensing properties of a new colorimetric chemosensor based on an hydrazone moiety

Resumo da comunicação eletrónica apresentada na 21st International Electronic Conference on Synthetic Organic Chemistry, 1–30 November 2017; Sciforum Electronic Conference Series, Vol. 21.It is reported the synthesis of one hydrazone derivative, functionalized with an heterocyclic moiety, in order to evaluate its photophysical properties and chemosensory ability. The new derivative was characterized by the usual techniques and a detailed photophysical study was undertaken. The evaluation of the novel compound as a colorimetric chemosensor was carried out by performing titrations in acetonitrile and acetonitrile/water in the presence of relevant organic and inorganic anions, and of alkaline, alkaline-earth and transition metal cations.Thank are due to Fundação para a Ciência e Tecnologia (Portugal) and FEDER-COMPETE for financial support through Centro de Química (UID/QUI/00686/2013 and UID/ QUI/0686/2016), and a PhD grant to R.C.M.
