Improving the sensing ability of thiazolothiazole derivatives towards metal ions
Publication . F. R. Cerqueira, Ana; M. M. Moura, Nuno; Neves, Maria G. P. M. S.; Jorge Parola, A.; Tomé, Augusto C.; LAQV@REQUIMTE; DQ - Departamento de Química; Elsevier
Two non-symmetrical thiazolothiazoles (TzTz) incorporating pyridin-2-yl groups were synthesized and their sensing abilities towards a series of metal ions were evaluated. The new compounds exhibited good sensing capabilities towards Cu2+ and Zn2+, enabling the differentiation between these two metal ions through spectrophotometric and spectrofluorimetric titrations. The addition of other metal ions to these TzTz derivatives does not cause noticeable effects. The results of this study highlight the high potential of TzTz derivatives for metal ions detection applications.

Thiazolo[5,4-d]thiazoles are valuable materials for a range of technical and biological applications. They are used as chemosensors, electroluminescent materials, organic light-emitting diodes (OLEDs), in solar cells, in live-cell imaging, etc., and for those applications π-extended thiazolo[5,4-d]thiazole derivatives are particularly attractive. A convenient synthetic route to non-symmetrical thiazolo[5,4-d]thiazoles bearing styrylpyridyl or hetarylvinylpyridyl groups, and their absorption and emission properties, is reported.
