Knoevenagel and Wittig condensation reactions new fluorescent, differently functionalized oligo(2,6-naphthylenevinylene)s have been synthesized, the presence of terminal aldehyde or bromine substitution opening the way to the incorporation of the fluorescent trimers in a variety of polymeric materials. The effect of substituting the phenylene ring by the more bulky dialkoxynaphthalene system in arylenevinylene-type
提出了适当的萘环对称和不对称官能化的合成策略。通过 Knoevenagel 和 Wittig 缩合反应,合成了新的荧光、不同功能化的低聚(2,6-亚萘基亚乙烯基),末端醛或溴取代的存在为将荧光三聚体掺入各种聚合物材料开辟了道路. 从结构的角度研究了在亚芳基亚乙烯基型材料中用体积更大的二烷氧基萘体系取代亚苯基环的效果,以及通过引入亚萘基亚乙烯基和氰基取代的亚萘基亚乙烯基单元来调节发射颜色和电子亲和力的可能性。也进行了调查。
