Tuning Of Azine Derivatives For Selective Recognition Of Ag Plus With The In Vitro Tracking Of Endophytic Bacteria In Rice Root Tissue

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.
