resumo
Several azine derivatives have been prepared and structurally characterized by spectroscopic and single-crystal X-ray diffraction analysis. Two of them, viz. naphthalene based (A10) and anthracene based (A11) show fluorescence enhancement in the presence of Ag+ in aqueous-methanol. Moreover, A11 efficiently tracks Ag+ in vitro endophytic bacteria infected rice root tissue. Experimental results have been substantiated by theoretical DFT calculations.

AG is grateful to BU for fellowship. We thank Dr A Banerjee, Department of Chemistry & Biochemistry, the University of Texas at Austin, USA for routine cell imaging studies. We sincerely acknowledge USIC, BU for providing the XRD facility for some ligands. The single crystal X-ray structure determinations were also carried out at the University of Aveiro, supported by FCT/MEC via financial support to the CICECO-Aveiro Institute of Materials (FCT UID/CTM/50011/2013) and the iBiMED-Institute of Biomedicine (FCT UID/BIM/04501/2013) through national funds and, when applicable, co-financed by FEDER, within the PT2020 Partnership Agreement.
