具有蓝/蓝双光子激发荧光的新型1 H-咪唑并[4,5- f ] [1,10]菲咯啉衍生物的绿色合成和光物理性质
摘要:
已开发出一种简单,快速且高效的方法来合成一系列新型的1 H-咪唑并[4,5- f ] [1,10]菲咯啉衍生物(1BN,2Py,3BI,4BT和5MOBI)通过无溶剂条件下的三组分一锅法反应。其结构的特征在于FT-IR,1 H NMR,1313 C NMR,MS和元素分析。在各种溶剂中系统地研究了它们的光物理性质,包括线性吸收,单光子激发荧光,双光子吸收和双光子激发荧光。结果表明,所有化合物均发出相对较强的蓝/青色荧光。1BN和5MOBI在THF中显示出较大的双光子吸收截面(471和654 GM)。此外,使用密度泛函理论研究了电子结构与光物理性质之间的关系。

Novel paramagnetic materials (3a, 3b, 4a and 4b) based on heterocyclic dyes (2a and 2b) and one stable nitroxide radical (4-NH2-TEMPO) were synthesized. EI-MS, elemental analysis and FT-IR spectral data confirmed the structures of the newly synthesized compounds. In addition, the cyclic voltammetry, the antioxidant activity and reactive oxygen species (ROS) scavenging properties of these compounds
