Abstract
A diarylethene molecular switch has been used within an energy transfer scheme to affect the electron injection efficiency of an organic dye sensitiser attached to a titania nanoparticle.
Highlights
Modulating electron injection from an organic dye to a titania nanoparticle with a photochromic energy transfer acceptor†
When DTE is in its ring-open form (o-DTE), the excited D35 is unaffected and undergoes electron injection into the titania conduction band
When DTE is in its ring-closed form (c-DTE), the excited D35 undergoes D35 - c-DTE Forster Resonance Energy Transfer (FRET), lowering the efficiency of electron injection
