A facile route for the synthesis of luminescent and light refractive polymers is proposed. Silole-containing diyne and halogenated tetraphenylethene derivatives are synthesized and their coupling reactions furnish poly(arylene ethynylene)s with high molecular weights in high yields. All of the polymers are soluble and film-forming and possess a high thermal stability. They emit strong green lights when their solutions and nanoparticle suspensions are photoexcited. The polymers show high refractive indices with low chromatic dispersions. Their RI values can be modulated and their thin films can be crosslinked using UV irradiation, generating negative photoresist patterns.
提出了一种简便的合成发光和光折射聚合物的方法。合成了含硅杂环二炔和卤代四苯乙烯衍生物,它们的偶联反应以高产率得到了高分子量的聚(芳基乙炔)。所有聚合物均具有良好的溶解性和成膜性,热稳定性高。其溶液和纳米颗粒悬浮液在光激发下会发出强烈的绿光。聚合物具有高折射率和低色散。其 RI 值可以通过 UV 辐射进行调节,并且可以使用交联生成负性光致抗蚀剂图案。
