A new tetrathiafulvalene–phenoxynaphthacenequinone dyad: switching on the intramolecular electron-transfer with UV light irradiation and metal ion coordination
The metal ion-promoted intramolecular electron transfer within TTF-based dyad 1 containing a photochromic PNQ unit can be switched on with UV light irradiation by taking advantage of the photochromic feature of the PNQ unit and the fact that the trans and ana forms of PNQ show different electron accepting capacity.
