Structural phase transitions initiating the Peierls transition in di-perylene hexafluorophosphate

Electron Spin Resonance: A Major Probe for Molecular Conductors

“…Cation radical salts have been obtained with arenes, − like pyrene, , perylene, − fluoroanthene, − or naphthalene . These molecules being only composed of light elements, i.e., carbone and hydrogen, the effect of the spin−orbit coupling is minimized and extremely narrow EPR line width have been obtained.…”
