dc.description.abstractA serious of pyridine based Schiff bases (M1, M2, and M3) were synthesized via condensation reaction of 4-aminosalicyclic acid with 2-pyridinecarboxaldehyde, 3-pyridine carboxyaldehyde and 4-pyridinecarboxaldehyde, respectively. The transformation of Schiff bases into their poly(phenoxyimine) species (P1, P2, P3) was obtained using oxidative polycondensation (OP) by NaOCl as the oxidant in alkaline medium at 70 degrees C. The structures of the synthesized compounds were characterized by solubility test, FT-IR, UV-Vis and NMR techniques. Thermal data were obtained by TG-DTA and DSC techniques. Photoluminescence (PL) properties of the synthesized materials were examined in organic solvent. Fluorescence measurements were carried out in various concentrated solutions to determine the optimum concentrations and PL intensities. P3 could be used in light-emitting diodes due to its multi-color (white, blue, green and yellow) light-emitting property. The efficiency (eta) of a solar cell of P1, P2 and P3 were determined by single channel Potentiostat/Galvanostat with electrochemical impedance spectroscopy. The order of conductivities was found to be as P3>P2>P1 as a result of iodine doping. The best performing photovoltaic cell with I-sc (mA cm(-2)), V-oc (V), FF, and eta (%) as -0.642, 0.399, 0.461 and 0.118 was obtained for P3. (C) 2018 Elsevier B.V. All rights reserved.
