摘 要: 基于实现铂乙炔化合物光限幅材料的固态化和实用化的目的,通过分子设计合成了一种新型的含氟端基的铂芳香炔单体,并通过亲核反应的方式将其引入到聚芳醚主链中,制备出了溶解性优异的含铂乙炔基团的聚芳醚共聚物,最后通过流延法制备了固态光限幅膜材料。对单体和聚合物进行了结构、热性能、力学性能以及光物理表征,并对聚合物溶液和固态膜材料的非线性光学性能进行了研究。结果表明,该共聚物制成的固态膜材料具有较好的光限幅能力,同时也兼具了聚芳醚优异的热力学性能和机械性能。该研究结果为激光防护材料的固态化、实用化发展提供了新思路。
关 键 词: 高分子化学;光限幅材料;z-扫描;聚芳醚;铂乙炔

Abstract: In pursuit of achieving the practical solid-state application of platinum acetylide compounds as optical limiting materials, a novel fluorine-terminated platinum acetylide monomer was designed and synthesized. This monomer was then introduced into the backbone of poly(arylene ether)s via nucleophilic reactions, resulting in the preparation of copolymers with excellent solubility. Subsequently, solid-state optical limiting films were fabricated by casting. The structures, thermal, mechanical, and optical properties of both monomers and polymers were thoroughly characterized, and the nonlinear optical properties of both the polymer solution and the solid film were investigated. The results demonstrated that the solid-state films derived from this copolymer exhibited superior optical limiting capabilities, while maintaining the excellent thermodynamic and mechanical properties inherent to poly(arylene ether)s. This research provides novel insights for the development and practical utilization of solid-state laser protection materials.
Key words: polymer chemistry; optical limiting materials; z-scan; poly(arylene ether)s; platinum acetylide
