are molecular systems that undergo a photolysis with the evolution of molecular nitrogen. A set of aryltriazene bearing different substituents are synthesized and characterized. The photoreaction is studied in solution by means of UV–vis spectroscopy showing a large dependence of required doses and UV–vis spectrum evolution on the substituent position and character. The structural changes upon the
三氮烯是随着分子氮的演化而经历光解的分子系统。合成并表征了一组带有不同取代基的芳基三氮烯。通过紫外-可见光谱在溶液中研究光反应,显示所需剂量和紫外-可见光谱演变对取代基位置和性质有很大的依赖性。还使用振动光谱(IR 和拉曼)探测光解后的结构变化。此外,GC-MS 光谱用于检索主要光产物的结构。就稳定性和谱带位置而言,最有希望的衍生物被掺入不同的聚合物基质中,包括热固性和热塑性塑料;它的光反应与聚合物结构相关。
