Observation of the solid-state formation of a TTF-CA complex by terahertz spectroscopy

The solid-state synthesis of a tetrathiafulvalene-chloranil (TTF-CA) complex was demonstrated, and progress in the formation of the complex was monitored using a GaP Raman terahertz (THz) spectrometer. Clear transitions in the THz absorption spectra indicated that the mixture of TTF and CA became the black phase TTF-CA complex. The results of X-ray diffraction, Raman scattering, and FTIR spectra are presented as supporting evidence. supporting evidence.(c) 2008 Elsevier B.V. All rights reserved.
