Abstract

The possibility of using a series of methacrylate-containing N,N-diethyl-4-(phenyldiazenyl)anilines with various para-substituents (–H, –Br, –NO₂) relative to the azo group as photoinitiators of radical polymerization is considered. The electrochemical and photoluminescent properties of these compounds have been studied. In the presence of azo dyes, two-photon photopolymerization of pentaerythritol triacrylate was carried out using focused 780-nm radiation from a femtosecond laser. Structures with minimal dimensions of linear elements of 94 ± 5 nm were obtained by means of the DLW nanolithography technique, and 3D microstructures of complex architecture were fabricated.

作为双光子聚合引发剂的 N,N-二乙基-4-(苯基二氮)苯胺的甲基丙烯酸酯-С-含对衍生物

摘要研究考虑了使用一系列相对于偶氮基团具有不同对位取代基（-H、-Br、-NO2）的含甲基丙烯酸酯的 N,N-二乙基-4-（苯基二氮基）苯胺作为自由基聚合的光引发剂的可能性。对这些化合物的电化学和光致发光特性进行了研究。在偶氮染料存在的情况下，使用飞秒激光器发出的 780 纳米聚焦辐射对季戊四醇三丙烯酸酯进行了双光子光聚合反应。通过 DLW 纳米光刻技术获得了线性元素最小尺寸为 94 ± 5 nm 的结构，并制造出了结构复杂的三维微结构。
