  "abstract": "Novel organic semiconductor poly(azomethine) materials were synthesized via the polycondensation of terephthalaldehyde with two distinct diamines: para-phenylenediamine and 4,4’-diaminodiphenylmethane. These synthetic routes yielded a fully conjugated polyimine (P1) and a polyimine featuring a more restricted conjugation domain interrupted by a methylene spacer (P2), respectively. A comparative study was conducted to evaluate the influence of the conjugation length on some of their properties, mainly optoelectrical. Hydrochloric acid was employed as a dopant to enhance the electrical performance of the synthetized macromolecules. Furthermore, in alignment with eco-design principles to promote renewable and sustainable solutions, these polymers were integrated onto cellulosic supports either through physical deposition on cellulose filaments or via covalent grafting onto propargylated Kraft pulp fibers using copper(I)-catalyzed azide-alkyne cycloaddition (CuAAC). Structural, morphological, and optical characterizations, including Fourier-transform infrared (FTIR) and UV-Visible spectroscopies, solid-state 13C NMR, X-ray photoelectron spectroscopy (XPS), scanning electron microscopy (SEM), and atomic force microscopy (AFM), confirmed the successful synthesis, functionalization, and fabrication of the biocomposite materials. Conductivity measurements and optical band gap (Eg) estimations revealed that the conformational flexibility of polymer P2 promotes tighter molecular packing and effective inter-chain interactions (π-π stacking), thereby enabling the development of bio-based semiconductor materials with promising potential for organic electronics.",
