Abstract
AbstractA novel azine monomer and its oligomeric esters were synthesized and applied to chemosensor applications. Among the series of metal ions, the fluorophores show selective and sensitive “turn off” response towards Ag+ ions. The stoichiometry and binding constant are calculated using the Stern‐Volmer equation and Benesi‐Hildebrand plots, respectively. The fluorophore‘s capability for quantitative analysis of Ag+ ions was studied. The quenching mechanism LMCT and PET behind the “turn off” response was confirmed. The conductivity nature of iodine doped and undoped oligoesters was studied. The dielectric behaviour of oligoesters was also studied to determine the possibility of oligoesters in making passive components such as capacitors and resistors. All the results obtained from chemosensor and electrical studies were validated using a theoretical (DFT) analysis using B3LYP/6–311++G(d,p) level basis set.
