- Abstract
- A series of quinoidal oligothiophenes have been investigated by means of solid-state Fourier-transform (FT)-Raman and
electron spin resonance (ESR) spectroscopies complemented with density functional theory calculations. FT-Raman spectra recorded
as a function of temperature show that, upon laser irradiation, the molecules undergo a reversible structural evolution
from a quinoid-type pattern at low temperature to an aromatic-type pattern at high temperature. Moreover, ESR spectra show
that a portion of these compounds exists in a biradical state at room temperature. These seemingly disconnected findings and
others, such as conformational isomerism, are consistently explained by the consideration of biradical species associated with
the presence of low-lying triplet electronic states. In addition to the well-established versatility of quinoidal oligothiophenes regarding
ambipolar electrical actuation in field-effect transistors, the exhibition of dual electrical and magnetic behavior leads to
the prospect of new materials that have tunable electrical, optical, and magnetic properties. (literal)
