Optical detection of magnetic resonance on triplet states in organic crystals

The variety of experiments combining the means of optical spectroscopy with those of electronspin-resonance is demonstrated on the 1:1 CT- crystal anthracene/tetrachlorophtalic anhydride using different excitations (S 0 → S 1-band, S 0 → S 1-traps and S 0 → T 1-band) as well as different emissions (...

Summary:The variety of experiments combining the means of optical spectroscopy with those of electronspin-resonance is demonstrated on the 1:1 CT- crystal anthracene/tetrachlorophtalic anhydride using different excitations (S 0 → S 1-band, S 0 → S 1-traps and S 0 → T 1-band) as well as different emissions (phosphorescence, fluorescence and delayed flourescence). The experiments revealed the properties of the triplet states of various traps, one of these exhibiting excitonic character. In β-9,10-dichloroanthracene one-dimensional excitons are found via the DF-ODMR whose frequency is influenced by thermally activated interstack scattering.
