| 抄録: | Lithium intercalation compounds of α- and β-perylene are investigated by photoelectron spectroscopy. Spectroscopic data together with a Born-Haber cycle provide information on the formation enthalpy of those materials. This approach allows understanding the amount of charge transferred from the alkali metal atoms to the π system, and illuminates the role of molecular versus solid-state properties in the formation of the intercalation compounds. In the bulk of α-perylene material, molecular dimerization survives upon intercalation which reduces the Madelung energy of the intercalation compound but increases the electron-accepting capability of the organic system and facilitates the ionization of lithium atoms in the molecular solid environment. The lower ionization potential results in a larger charge transfer (about two electrons per molecule) in α-perylene compared to the monomeric system, β-perylene. |
