as novel photoactivatable CO-releasing molecules (PhotoCORMs). The influence of the imine vs. amine group in the ligands on the electronic structure and the photophysical behavior was investigated with the aid of DFT and TDDFT calculations. Solution IR studies on selected compounds allowed identification of intermediates resulting from the photoreaction. Finally, light-induced CO release from a model
基于三齿双(吡唑基)乙胺(bpea)的五种通式为[Mn(bpea N CHC6H4R)(CO)3 ] PF 6和[Mn(bpea NHCH2C6H4R)(CO)3 ] PF 6的锰(I)三羰基配合物)合成并充分表征了每个配体,每个配体均包含一个带有4个取代基的侧基,R = H,I和C C–H,包括X射线结构分析的三种化合物。所有复合物在黑暗中在水性缓冲液中稳定较长时间。但是,CO释放可以通过在365 nm处照射来触发,从而将这些化合物确立为新型的可光活化的CO释放分子(PhotoCORM)。亚胺的影响与。借助DFT和TDDFT计算研究了电子结构和光物理行为的配体中的胺基。通过对所选化合物进行溶液IR研究,可以鉴定出由光反应产生的中间体。最后,使用COP-1作为荧光开关探针,在PBS缓冲液中和体外在人脐静脉内皮细胞(HUVEC)中都证明了光诱导的CO从模型化合物释放。
