Title: Perovskite Photocatalysis. Methyl Viologen Induces Unusually Long-Lived Charge Carrier Separation in CsPbBr 3 Nanocrystals

Abstract

The strong binding between CsPbBr3 nanocrystals and methyl viologen induces a long-lived charge-separated state following band gap excitation with important implications in photocatalytic processes. The unusually long-lived bleaching of the CsPbBr3 excitonic peak in this case arises from the creation of a dipole with the hole residing in CsPbBr3 and the electron in the surface-bound methyl viologen moiety.
