Synthesized monomers were then converted into their oligomeric derivatives via oxidative polycondensation carried out using NaOCl. The structural, thermal, optical, electrochemical, and morphological properties of the obtained monomers were comprehensively characterized using fourier transform infrared (FT\u2010IR), proton nuclear magnetic resonance (\n                    <jats:sup>1<\/jats:sup>\n                    H\u2010NMR), carbon\u201013 nuclear magnetic resonance (\n                    <jats:sup>1<\/jats:sup>\n                    <jats:sup>3<\/jats:sup>\n                    C\u2010NMR), ultraviolet\u2010visible spectrophotometer (UV\u2013vis), thermogravimetry\u2010derivative thermogravimetry (TG\u2010DTG), and cyclic voltammetric analyses. Spectroscopic studies confirmed the successful synthesis of Schiff bases and the presence of stable azomethine bonds. Molecular weight, glass transition temperature, and surface morphologies of oligomers were determined by gel permeation chromatography (GPC), differential scanning calorimetry (DSC), and field emission scanning electron microscope (FE\u2010SEM) measurements, respectively. The M\n                    <jats:sub>n<\/jats:sub>\n                    values of oligo(3\u2010APPHNA) and oligo(4\u2010APPHNA) were found to be 3400 and 2900\u00a0Da, respectively. The results revealed an oxidative oligomerization process yielding relatively narrow molecular weight distributions. Oligo(4\u2010APPHNA) has shown more pronounced semiconductor properties compared to other oligomers, considering its 2.30\u00a0eV optical band gap and frequency\u2010dependent electrical behavior. Additionally, dielectric measurements showed that oligo(4\u2010APPHNA) exhibited higher dielectric constant, dielectric loss, and AC conductivity values throughout the investigated frequency range. These findings suggest that the synthesized oligomers are promising candidate materials for future optoelectronic and semiconductor applications, but further research at the device level is needed.\n                  <\/jats:p>","DOI":"10.1002\/marc.70403","type":"journal-article","created":{"date-parts":[[2026,8,17]],"date-time":"2026-08-17T02:06:59Z","timestamp":1786932419000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Oxidative Polycondensation of Pyrazolone\u2010Based Schiff Bases: Synthesis, Structural Characterization, Thermal and Electrical Properties"],"prefix":"10.1002","volume":"47","author":[{"given":"Adnan","family":"Solmaz","sequence":"first","affiliation":[{"name":"Department of Chemistry Polymer Synthesis and Analysis Lab \u00c7anakkale Onsekiz Mart University  \u00c7anakkale T\u00fcrkiye"},{"name":"Strategic Raw Materials and Advanced Technology Applications Department Munzur University  Tunceli T\u00fcrkiye"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0401-7419","authenticated-orcid":false,"given":"Re\u015fit","family":"\u00c7akmak","sequence":"additional","affiliation":[{"name":"Department of Chemistry Polymer Synthesis and Analysis Lab \u00c7anakkale Onsekiz Mart University  \u00c7anakkale T\u00fcrkiye"},{"name":"Department of Medical Services and Techniques Vocational School of Health Services Batman University  Batman T\u00fcrkiye"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9813-2962","authenticated-orcid":false,"given":"\u0130smet","family":"Kaya","sequence":"additional","affiliation":[{"name":"Department of Chemistry Polymer Synthesis and Analysis Lab \u00c7anakkale Onsekiz Mart University  \u00c7anakkale T\u00fcrkiye"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2026,8,16]]},"reference":[{"key":"e_1_2_8_2_1","doi-asserted-by":"publisher","DOI":"10.3390\/molecules23010134"},{"key":"e_1_2_8_3_1","doi-asserted-by":"publisher","DOI":"10.1080\/00958972.2023.2201655"},{"key":"e_1_2_8_4_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.molstruc.2017.09.015"},{"key":"e_1_2_8_5_1","doi-asserted-by":"publisher","DOI":"10.1021\/om300602w"},{"key":"e_1_2_8_6_1","doi-asserted-by":"publisher","DOI":"10.1080\/00958972.2019.1641702"},{"key":"e_1_2_8_7_1","doi-asserted-by":"publisher","DOI":"10.1080\/00958972.2019.1630613"},{"key":"e_1_2_8_8_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.molstruc.2018.09.095"},{"key":"e_1_2_8_9_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.jscs.2010.02.010"},{"key":"e_1_2_8_10_1","doi-asserted-by":"publisher","DOI":"10.1080\/00958970802326179"},{"key":"e_1_2_8_11_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.molstruc.2019.127603"},{"key":"e_1_2_8_12_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.saa.2019.117596"},{"key":"e_1_2_8_13_1","doi-asserted-by":"publisher","DOI":"10.2165\/00003495\u2010198600324\u201000006"},{"key":"e_1_2_8_14_1","doi-asserted-by":"publisher","DOI":"10.1016\/S1366\u20100071(97)80033\u20102"},{"key":"e_1_2_8_15_1","doi-asserted-by":"publisher","DOI":"10.1248\/cpb.c13\u201000314"},{"key":"e_1_2_8_16_1","first-page":"707","article-title":"Synthesis, Characterization and Biological Evaluation of Novel Pyrazole Ring Contain Mannich Derivatives","volume":"4","author":"Sureshkumar E.
