The structure of the synthesized material was identified by Fourier-transform infrared (FT-IR) spectroscopy (Bruker VERTEX 80v, Berlin, Germany). The ¹H NMR spectra were confirmed with a Bruker DPX 200 MHz NMR spectrometer (Berlin, Germany) and were referenced to tetramethylsilane (TMS). Elemental analyses were carried out in a PerkinElmer Model 2400 CHNS/O analyzer.
Differential scanning calorimeter (DSC; NETZSCH 404 F3 Pegasus®), thermogravimetric analyzer (TGA; TA Q500), and thermomechanical analyzer (TMA-2940) were used in the same conditions as the previously published papers.^37,38 In particular, TMA was measured in the range of 30–230 °C. For the tensile properties of the film, a universal testing machine (UTM, Instron model 5564) was used, and the size of the film was 5 mm × 70 mm.
The color intensity of the Co-PAI film obtained according to the BPA molar ratio was measured with a Minolta spectrophotometer (CM-3500d). Yellow index (YI) measurements of the films were carried out at an observational angle of 10°, using a CIE-D illuminant. A Shimadzu UV-3600 spectrophotometer was used to obtain the UV-vis value of the film.

Thin layer chromatography was performed on pre-coated silica gel plates (Kiesel gel 0.25 mm, 60 G F 254, Merck, Munich, Germany), and the solvent system used was chloroform/methanol (7:3). The spots were detected under ultraviolet light. The melting points were measured (uncorrected) using a melting point apparatus (Sanyo Gallen Kamp, Cambridge, UK). IR spectra were obtained using an FT-IR spectrophotometer (Perkin Elmer, Massachusetts, USA). NMR spectra were acquired in DMSO-d₆ using an NMR spectrophotometer (Bruker AXS Inc., Zurich, Switzerland) operating at 500 MHz for ¹H and 125.76 MHz for ¹³CNMR. The chemical shifts were reported in δ values (ppm) relative to tetramethylsilane as the internal standard. Mass spectra were run on the direct inlet part of the mass analyzer in Thermo Scientific GCMS model ISQ LT (Massachusetts, USA). The elemental analyses were conducted on a model 2400 CHNSO analyzer (Perkin Elmer, Massachusetts, USA). The starting material, 4-chloro-7-methoxyquinoline 1, and the sulfonamide derivatives were obtained from Sigma-Aldrich.

Uncorrected melting points were determined using a Gallen Kamp melting point apparatus (Sanyo Gallen Kamp, UK). For thin layer chromatography, precoated silica gel plates (Kieselgel 0.25 mm, 60 F254, Merck, Germany) were utilized. Applying an n-hexane/ethyl acetate (8:2) developing solvent mixture, the spots were identified using ultraviolet light. An FT-IR spectrophotometer (Perkin Elmer, USA) was used to record the IR spectra (KBr disc). On an NMR spectrophotometer (Bruker AXS Inc., Switzerland) operating at 500 and/or 400 MHz for ¹H and 125.76 MHz for ¹³C, NMR spectra were scanned. Chemical shifts were measured using DMSO-d₆ and are given as δ-values (ppm) in relation to an internal standard tetramethyl silane. A model 2400 CHNSO analyzer (Perkin Elmer, USA) was used to perform elemental analysis. Each value measured was within ± 0.4% of the theoretical values. The reagents used were all of AR grade.

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
