港湾位取代苝二酰亚胺的合成与光催化有机反应性能研究港湾位取代苝二酰亚胺的合成与光催化有机反应性能研究

摘要：

本文针对苝二酰亚胺的不足，采用港湾位取代的方式，成功合成了一系列新型苝二酰亚胺衍生物。通过核磁共振、质谱等手段对其化学结构进行了表征。同时，运用紫外-可见漫反射光谱技术研究了新型苝二酰亚胺衍生物固体的光催化性能。结果表明，港湾位取代后的苝二酰亚胺衍生物具有更好的光催化性能，同步也展现了更好的化学稳定性。

此外，利用本文中合成的苝二酰亚胺衍生物，进行了光催化反应研究。实验结果表明，在紫外光照射下，苝二酰亚胺衍生物表现出良好的催化性能，可催化芳香胺与芳香醛反应，生成对应的亚胺化合物。在研究中，我们发现，催化剂的光吸收性能与其催化活性密切相关。同时，合理调节反应条件及催化剂用量也能够进一步提高反应收率。本文的研究结果为苝二酰亚胺衍生物及其港湾位取代衍生物在光催化有机反应方面的应用提供了新的思路和方法。
