In this work, we present the innovative synthesis of salophen (acetaminosalol) derivatives in a solvent-free environment by high-speed ball milling, using non-conventional activation method, which allowed obtaining compounds shorter time and with better yield. Furthermore, for first time, were deposited as composite films, matrix poly 3,4-ethylene dioxythiophene:polystyrene sulfonate (PEDOT:PSS) polymer. Significant findings include transformation from benzoid to quinoid form PEDOT post-IPA treatment, evidenced Raman spectroscopy. SEM analysis revealed formation homogeneous AFM provided insights into changes surface roughness morphology may be crucial understanding potential applications electronics. The optical bandgap ranges between 2.86 3.2 eV PEDOT:PSS-salophen placing them organic semiconductors. electrical behavior films undergoes increase voltage, ohmic space charge-limited conduction, subsequently constant current, maximum 20 mA. These results suggest possible use

Web-based discussion tools have emerged as valuable platforms in teaching and learning chemistry. Despite the increasing use of web-based tools, their effectiveness enhancing cognitive, social, aspects organic chemistry remains underexplored. Therefore, this review aims to address gap by synthesizing relevant literature on these key dimensions. The study adopted a scoping for comprehensively mapping, exploring, clarifying existing body literature. PRISMA was used extract 57 kinds from electronic databases that are Scopus, ISI, Google Scholar, ERIC, Web Science, academia, digital citation. Descriptive statistics analyze current trends cognitive while thematic analysis social aspects. results revealed predominately predominantly utilized at university level (52%) compared secondary schools (48%) more common developed countries than least ones. Moreover, positive impact fostering students' conceptual understanding interaction through proper guidance teachers. However, some critical issues such poor internet, quality discussion, lack hands-on experience, complexity molecular structures, tactile were identified challenges hindering effective implementation tools.
