High-potential photo-oxidants are provided with a supermolecule structure at least including a conjugated macrocycle linked to a metal complex. The conjugated macrocycle is electron-accepting relative to hydrogen or bears electron withdrawing substituents such as fluoroalkyl, fluoroaryl, fluoro, halo, cyano, or nitro. The metal complex is also electron-accepting relative to hydrogen or bears electron withdrawing substituents such as fluoroalkyl, fluoroaryl, fluoro, halo, cyano, or nitro. The linker can be thynyl, vinyl, thiophenyl, diethynylaryl, divinylaryl, diethynyl (unsaturated heterocycloalkenyl), divinyl (unsaturated heterocycloalkenyl), diethynyl (unsaturated heterocycloalkynyl), or divynyl (unsaturated heterocycloalkynyl). A specific implementation is an ethyne-bridged eDef-Rutpy-(porphinato)Zn(II) (eDef-RuPZn) supermolecule.
高潜能的光氧化剂具有至少包括一个共轭大环与金属配合物相连的超分子结构。共轭大环相对于氢原子是电子受体的,或者带有电子吸引取代基,例如氟烷基、氟芳基、氟、卤素、氰或硝基。金属配合物相对于氢原子也是电子受体的,或者带有电子吸引取代基,例如氟烷基、氟芳基、氟、卤素、氰或硝基。连接器可以是炔基、乙烯基、噻吩基、二炔基芳基、二乙烯基芳基、二炔基(不饱和杂环烯基)、二乙烯基(不饱和杂环烯基)、二炔基(不饱和杂环炔基)或二乙炔基(不饱和杂环炔基)。一个具体的实现是一个以乙炔为桥的eDef-Rutpy-(porphinato)Zn(II)(eDef-RuPZn)超分子。
