Spiro rhodamine (Rho)-naphthalenediimide ( NDI ) electron donor-acceptor orthogonal dyads were prepared to generate a long-lived charge separation (CS) state based on the electron spin control approach, i.e. to form the 3 CS state, not the 1 CS state, to prolong the CS state lifetime by the electron...
