二乙炔类聚合物是一类以1,3-丁二炔为主要聚合单体的重要聚合物,应用于有机发光器件[1]、太阳能电池[2]、磁性材料[3]、光纤传导[4]、分子传感器[5]、药物[6]等领域.中间体二炔化合物是构建分子的基本模块之一[7],不仅是有机合成的重要中间体,也是天然产物和生理活性化合物的基本骨 Diacetylene polymers are a class of important polymers with 1,3-butadiyne as the main monomer. They are used in organic light-emitting devices [1], solar cells [2], magnetic materials [3] 4], molecular sensors [5], drugs [6], etc. Intermediates Diacetylene compounds are one of the basic building blocks for building molecules [7] and are not only important intermediates for organic synthesis but also natural products and physiologically active compounds Basic bone
