Synthesis and Photophysical Properties of Bis-Palladium Complexes of Doubly N-Confused Calix6phyrin(1.1.1.1.1.1)

摘要

Singlet oxygen (~1△_2) is one of the most important reactive oxygen species (ROS) and plays key role in many photoinduced oxidative processes in biological/chemical systems.[1] Owing to its wide applications in the photodynamic therapy and photooxidation of proteins/DNA bases, many heavy metal (Pd, Pt, Ir, etc.)-based complexes have been studied as triplet photosensitizers.[2] In this regard, we have recently reported platinum complexes of N-confused calix[4]phyrin, showing efficient singlet oxygen generation capabilities.[3]
