“…When oxidant was added to reaction mixture, the color of reaction medium was turned black. The reaction was carried out at reflux for 14 h and then reaction mixture was neutralized with an equivalent amount of 0.1 M HCl solution 26,27 . The reaction product was filtered and the poly(8‐((4‐hydroxybenzylidene)amino)naphthalene‐2‐ol) (PANAPSB) was dried in a vacuum oven at 50°C for 24 h. The yield of PANAPSB was found to be 60%.…”

In this study, 8‐((4‐hydroxybenzylidene)amino)naphthalene‐2‐ol (ANAPSB) compound was synthesized from condensation reaction of 8‐amino‐2‐naphthol (ANAP) with 4‐hydroxybenzaldehyde and then ANAPSB and 8‐amino‐2‐naphthol were polymerized via oxidative polycondensation alkaline medium by H2O2 (35% aqueous solution) as oxidant at 70°C 14 h. The structures of compounds were confirmed by UV–Vis, 1H‐13C‐NMR and FT‐IR measurements. The surface morphologies of PANAP and PANAPSB were examined with SEM analyses. The electrochemical properties of 8‐amino‐2‐naphthol, poly(8‐amino‐2‐naphthol) (PANAP), ANAPSB and poly(8‐((4‐hydroxybenzylidene)amino)naphthalene‐2‐ol) (PANAPSB) were determined by cyclic voltammetry technique. The thermal properties of compounds were found by TG‐DTA analysis. The glass transition temperatures (Tg) of PANAP and PANAPSB were determined from DSC measurements. The Tg values of PANAP and PANAPSB were found to be 159 and 150°C, respectively. The Mn, Mw, Mp, Mz and PDI values of the PANAP and PANAPSB were calculated from gel permeation chromatography measurements. The optical and fluorescence properties of the compounds were determined by UV–Vis and fluorescence measurements, respectively. The optical band gap values of ANAP, PANAP, ANAPSB and PANAPSB were calculated as 3.12, 1.61, 2.79 and 1.57 eV, respectively.
