Iron-based photosensitizers, which can be used for solar energy conversion and photoluminescence applications, include an iron complex with N-heterocyclic carbene (NHC) ligands (FeNHC), a linking unit, and a polarizable unit formed of a pi conjugated structure having a one-electron reduction potential more positive than NHC.

Iron chromophores for energy conversion

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.
