Optically detected magnetic resonance studies of tetrathienylene vinylene

We have investigated films and dilute glasses of tetrathienylene vinylene (4TV) by optically detected magnetic resonance. We calculate the g-values of polarons and zero field splitting parameters for triplet excitons. The strength of the ODMR signals, but not their spectral lineshapes, are sensitive...

Description
Summary:We have investigated films and dilute glasses of tetrathienylene vinylene (4TV) by optically detected magnetic resonance. We calculate the g-values of polarons and zero field splitting parameters for triplet excitons. The strength of the ODMR signals, but not their spectral lineshapes, are sensitive to the sample concentration. Photoexcitation lifetimes were also estimated.
