The two parts in the dyads are connected via a spiro quaternary carbon atom, thus the torsion between the donor and acceptor is completely inhibited, which is beneficial to reduce the reorganization energy and to exploit the Marcus inverted region effect to prolong the CT state lifetime. Femtosecond transient absorption spectra show that the charge separation is rather fast, while nanosecond transient absorption spectra confirmed the formation of long‐lived CT state (2.6 μs). Time‐resolved electron paramagnetic resonance (TREPR) spectra determined the spin multiplicity of the long living state and assigned it to a <jats:sup>3</jats:sup>CT state. Replacement of an oxygen atom in the PI part with a sulfur atom favoring classical intersystem crossing processes, causes a consistently shortening of the lifetime of the <jats:sup>3</jats:sup>CT state (0.29 μs).</jats:p>"}]}],"creator":[{"@id":"https://cir.nii.ac.jp/crid/1380021394468628356","@type":"Researcher","foaf:name":[{"@value":"Xi Chen"}],"jpcoar:affiliationName":[{"@value":"State Key Laboratory of Fine Chemicals School of Chemical Engineering Dalian University of Technology  2 Ling Gong Road Dalian 116024 P.
