Recognition of transition metals by benzimidazoles with an optical response

Resumo da comunicação eletrónica d003 apresentada na 19th Int. Electron. Conf. Synth. Org. Chem., 1–30 November 2015; Sciforum Electronic Conference Series, Vol. 19.It is reported the interaction studies of a family of benzimidazoles attached to furan, pyrrole and thiophene with biologically important cations, through spectrophotometric and spectrofluorimetric titrations.Thanks are due to Fundação para a Ciência e Tecnologia (FCT-Portugal) and FEDER-COMPETE for financial support through Centro de Química [PEst-C/QUI/UI0686/2013 (FCOMP-01-0124-FEDER-037302)] and a PhD grant to C.I.C. Esteves (SFRH/BD/68360/2010). The NMR spectrometer Bruker Avance III 400 is part of the National NMR Network and was purchased with funds from FCT and FEDER.
