Spin delocalization in radical cations of organic oxygen compounds as revealed by long-range hyperfine interactions and solvent effects

Conference Snow, L D ; Williams, F

ESR evidence is presented for long-range /sup 1/H hyperfine interactions and thermally reversible solvent effects involving mainly the radical cations of aldehydes and ketones in Freon matrices. Long-range couplings to delta protons are found to be surprisingly large in the cations of acyclic, cyclic, and polycyclic carbonyl compounds. The conformational requirements for these large couplings are discussed in terms of facile spin transmission via a trans arrangement of C-C and C-H sigma bonds, the assumption of this trans-effect providing a rigorous and consistent analysis of the experimental results for both nonrigid and rigid molecular geometries.

Separating hyperfine from spin-orbit interactions in organic semiconductors by multi-octave magnetic resonance using coplanar waveguide microresonators

Journal Article Joshi, G. ; Miller, R. ; Ogden, L. ; ... - Applied Physics Letters

Separating the influence of hyperfine from spin-orbit interactions in spin-dependent carrier recombination and dissociation processes necessitates magnetic resonance spectroscopy over a wide range of frequencies. For this, we have designed compact and versatile coplanar waveguide resonators for continuous-wave electrically detected magnetic resonance and tested these on organic light-emitting diodes. By exploiting both the fundamental and higher-harmonic modes of the resonators, we cover almost five octaves in resonance frequency within a single setup. The measurements with a common π-conjugated polymer as the active material reveal small but non-negligible effects of spin-orbit interactions, which give rise to a broadening of the magneticmore »« less

Spectrally resolved hyperfine interactions between polaron and nuclear spins in organic light emitting diodes: Magneto-electroluminescence studies

Journal Article Crooker, S. A. ; Kelley, M. R. ; Martinez, N. J. D. ; ... - Applied Physics Letters

We use spectrally resolved magneto-electroluminescence (EL) measurements to study the energy dependence of hyperfine interactions between polaron and nuclear spins in organic light-emitting diodes. Using layered devices that generate bright exciplex emission, we show that the increase in EL emission intensity I due to small applied magnetic fields of order 100 mT is markedly larger at the high-energy blue end of the EL spectrum (ΔI/I ∼ 11%) than at the low-energy red end (∼4%). Concurrently, the widths of the magneto-EL curves increase monotonically from blue to red, revealing an increasing hyperfine coupling between polarons and nuclei and directly providing insight into the energy-dependentmore »« less
