摘要：

We report on a spectroscopic study on (anti)ferroelectricity in organic mixed-stack charge transfer complex TMB-TCNQ. This compound has two polytypes, both of which undergo contrasting phase transitions. The transition of the monoclinic crystal is interpreted in terms of neutral-ionic phase transition, while the tricllnic form undergoes a lattice dimerization driven by an electrostatic mechanism of ferroelectricity. © 1992, Taylor & Francis Group, LLC.
