Abstract
This study reports the design, synthesis, and characterization of a novel compound, 1,2,3-tris(7-bromo-2H-benzo[e][1], [3]oxazin-3(4H)-yl)guanidine (BGu-BZ), using triaminoguanidinium chloride (Gu-3NH2) as a precursor through a straightforward Mannich condensation reaction. The resulting benzoxazine monomer exhibited distinct fluorescence properties influenced by solvent polarity, with emission maxima shifting across solvents. Thermal curing of BGu-BZ at 220 °C yielded poly(BGu-BZ), a porous polymer with enhanced fluorescence emission and excellent thermal stability (Td10 = 381.5 °C). The cured polymer demonstrated a surface area of 43 m2/g and significant fluorescence shifts, confirming alterations in electronic structure and increased conjugation. The study highlights the solvatochromism behavior of both monomer and polymer, underscoring their potential for applications in luminescent technologies such as solvent sensing and optoelectronics. This work provides valuable insights into the structural-functional relationship in guanidine-functionalized benzoxazines, paving the way for advanced material applications.
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.
