Intersystem Crossing, Photo‐Induced Charge Separation and Regioisomer‐Specific Excited State Dynamics in Fully Rigid Spiro Rhodammine‐Naphthalene/Anthraquinone Electron Donor‐Acceptor Dyads

We prepared a series fully rigid spiro electron donor-acceptor orthogonal dyads, with closed form of rhodamine (Rho) as electron donor and naphthalene (Np)/anthraquinone (AQ) as electron acceptor, to access the long-lived triplet charge separation (
