Unconventional polymerization of thiophene siloxane oligomers. Optoelectronic behavior and computational calculations
Four novel siloxane-functionalized oligo(azomethine)s (o-AzThs) containing thiophene and alkyl-thiophene units were successfully synthesized via a high-temperature polycondensation reaction between dichlorodiphenylsilane and four diphenol monomers incorporating imine linkages. The resulting o-AzThs were characterized by spectroscopic methods (NMR, FTIR) and elemental analysis. These oligomers, composed for 4–9 repeating units per chain exhibited excellent solubility in common aprotic polar solvents, moderate molecular weights (Mn = 2.94–4.70 kDa), and narrow polydispersity indices (PDI ≈ 1.1). The new o-AzThs displayed thermal stability up to 223–370 °C and glass transition temperatures ranging from 56 to 91 °C. Optoelectronic analysis showed a broad absorption–emission behavior with bandgaps values of 2.36–2.52 eV, along with low HOMO energy levels (−5.24 to −5.36 eV) suggesting their potential applications in optoelectronic field.
期刊介绍:
European Polymer Journal is dedicated to publishing work on fundamental and applied polymer chemistry and macromolecular materials. The journal covers all aspects of polymer synthesis, including polymerization mechanisms and chemical functional transformations, with a focus on novel polymers and the relationships between molecular structure and polymer properties. In addition, we welcome submissions on bio-based or renewable polymers, stimuli-responsive systems and polymer bio-hybrids. European Polymer Journal also publishes research on the biomedical application of polymers, including drug delivery and regenerative medicine. The main scope is covered but not limited to the following core research areas:
Polymer synthesis and functionalization
• Novel synthetic routes for polymerization, functional modification, controlled/living polymerization and precision polymers.
Stimuli-responsive polymers
• Including shape memory and self-healing polymers.
Supramolecular polymers and self-assembly
• Molecular recognition and higher order polymer structures.
Renewable and sustainable polymers
• Bio-based, biodegradable and anti-microbial polymers and polymeric bio-nanocomposites.
Polymers at interfaces and surfaces
• Chemistry and engineering of surfaces with biological relevance, including patterning, antifouling polymers and polymers for membrane applications.
Biomedical applications and nanomedicine
• Polymers for regenerative medicine, drug delivery molecular release and gene therapy
The scope of European Polymer Journal no longer includes Polymer Physics.
