The correlation between the molecular structures of three corrole derivatives (PC: 5,10,15-triphenyl corrole, PFPC: 5,10,15-tris(pentafluorophenyl) corrole, MCPC: 5,10,15-tris(p-methoxycarbonylphenyl)corrole) and their efficiencies for singlet oxygen generation was studied. Introducing electron-withdrawing fluorine atoms into the PC moiety led to a significant enhancement in singlet oxygen generation and facilitated intersystem crossing (ISC) due to enhanced spin-orbit coupling. Cyclic voltammetry experiments revealed a desirable linear relationship between the quenching rate constants and the oxidation potentials of the three corrole derivatives, indicating that the substituent effect is a critical factor governing the oxidation potential of photosensitizers for singlet oxygen generation.

三种环氧衍生物的分子结构之间的相关性（PC：5,10,15-三苯基腐蚀，PFPC：5,10,15-三（五氟苯基）腐蚀，MCPC：5,10,15-三（对甲氧基羰基苯基）研究了它们的产生单线态氧的效率。将吸电子的氟原子引入PC由于增强的自旋-轨道耦合，该部分导致单线态氧产生的显着增强并促进了系统间交叉（ISC）。循环伏安法实验表明，淬灭速率常数与三种Corrole衍生物的氧化电位之间具有理想的线性关系，表明取代基效应是控制光敏剂产生单线态氧的氧化电位的关键因素。
