Abstract

Electron paramagnetic resonance (EPR) spectra of single crystals of the 1 : 1 charge transfer (CT) complex of N, N'-dimethyldihydrophenazine (M2P) and of tetracyanoquinodimethane (TCNQ) provide the first case of thermally activated, with ΔEp = 0.60 ± 0.06 eV, triplet spin excitons observed in an organic CT solid. The narrow EPR lines and resolved fine structure splittings indicate mobile triplets based on adjacent M2P+TCNQ- ion radicals above a largely neutral ground state.
