Abstract
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.
