Synthesis of Acylarylenes and Hyperbranched Poly(acylarylene)s by Metal-Free Cyclotrimerization of Alkynes無金屬催化環叁聚合成芳酰基衍生物及超支化聚芳酰基衍生物

總結: The present invention relates to a new method for the synthesis of triaroylbenzene by secondary amine and DMF-catalyzed cyclotrimerization of acetylenes. This method can be applied for the synthesis of new branched organic materials and polymers containing the triaroylbenzene moieties. The polymerization is a simple one-pot reaction,strictly regioselective and highly functionality-tolerant,giving oligomer and polymers with high yields. The resulting have been characterized by IR, 1H NMR and 13C NMR, from which satisfactory results have been obtained. The polymers are processible, easily film-forming,and thermally stable. The present invention can be blend with a variety of macromolecules for general use.

技術優勢: 1. High processability
2. High functional end group density
3. Low solution and intrinsic viscosity and thermal stability

技術應用: - Potential candidates for many applications such as optical, thermal devices

Title: Synthesis of acylarylenes and hyperbranched poly(acylarylene)s by metal-free cyclotrimerization of alkynes | Synthesizing acyl and aromatic acyl hyper-branched aromatic hydrocarbon by the metal ring of alkyne third reaction
Usefulness: Synthesis of acylarylenes and hyperbranched poly(acylarylene)s by metal-free cyclotrimerization of alkynes | Synthesizing acyl and aromatic acyl hyper-branched aromatic hydrocarbon by the metal ring of alkyne third reaction
Summary: (A) is useful in thermoset and photo-patterning (all claimed). (A) is useful for optical (light-emitting polymers, hole- or electron-transport materials, optical limiters), thermal (curable films and adhesives), electronic (negative resist) and magnetic devices. (A) is also useful to make a hybrid-polymer by incorporating metallic species into the (co)polymers.
Novelty: New polymer comprising e.g. tricarbonyl phenyl compounds, useful in thermoset and photo-patterning for optical e.g. light-emitting polymers, thermal e.g. curable films and adhesives, electronic and magnetic devices
