含长共轭取代基的丙烯酸酯的合成

Synthesis of a novel acrylate monomer bearing pendants

文章通过在具有一定共轭链长的芴寡聚物的分子末段引入醇羟基,把长共轭结构的芴寡聚物作为取代基引入丙烯酸酯类单体。利用核磁共振确定了目标产物的分子结构,合成的单体具有强烈的紫外吸收和光致发光性质,而且由于在丙烯酸酯引入了芴寡聚物,产物可以用旋涂的方法在石英玻璃表面成膜,其在溶液中和固体薄膜最大发光位置分别是412 nm和442 nm。

One fluorene-pendant monomer of acrylic ester （PF-acrylate） was synthesized. The PF-acrylate is photo-lumineseent（PL） because of introduction of long-chain conjugated unit of oligofluorene. The structure of target acrylate was confirmed by the means of NMR. The sythesized monomer is easily solved in the common solvent and thin-film can be formed by spin coating the surface of glass. Its strongest emission is at 412 nm in THF solution and at 442 nm in film state, respectively.
