An energy gap of a direct type with the size of approximately 0.23 eV is observed at ambient pressure. In the molecular vibration region, the absorption peaks due to the C=C stretching are observed at 1518 and 1504 cm-1, suggesting that the excess electrons are less localized in this substance compared to other 2:3 TCNQ complexes. The behavior of these peaks suggests that a phase transition takes place at 1.0 GPa. In the high-pressure phase the excess electrons tend to be more localized instead of being delocalized as indicated by the increasing of the energy spacing of those modes. The charge transfer degrees of the TCNQ molecules are estimated to be 0.60 and 0.80 (low pressure) and 0.56 and 0.88 (high-pressure phase)., http://www.informaworld.com/openurl?genre=article&issn=1563-5287&volume=442&issue=1&spage=147}, pages = {147--155}, title = {Pressure dependence of electron distribution along the TCNQ columns in (TEDA)2TCNQ3}, volume = {442}, year = {2005}, yomi = {スギモト, トヨナリ} }
