Synthesis, film-forming properties, and thermal and light sensitivity of N,N′-bis[4-hydroxy(alkoxy, acyloxy)-3-alkoxyphenylmethylidene]benzene-1,4-diamines
The synthesis of π-conjugated polymers via an environmentally friendly procedure is generally challenging. Herein, we describe the synthesis of divanillin-based polyazomethines, which are derived from a potentially bio-based monomer. The polymerization is performed in 5 min under microwave irradiation without any metallic catalyst, with water as the only by-product. The vanillin-based polyazomethines
通过环境友好的方法合成 π 共轭聚合物通常具有挑战性。在这里,我们描述了基于联香草醛的聚偶氮甲碱的合成,它衍生自一种潜在的生物基单体。在没有任何金属催化剂的情况下,在微波辐照下 5 分钟内进行聚合,水是唯一的副产物。通过 SEC、TGA 和 UV-Vis 光谱对基于香草醛的聚偶氮甲碱进行了表征。通过 X 射线衍射和 UV-Vis 光谱设计和表征模型化合物。用作模型的基于香草醛的甲亚胺的结构/性能研究使我们能够明确地确认 E 构型并突出基于香草醛的聚合物的交叉共轭性质。
