Multistage control of near-infrared and magnetic properties <i>via</i> π-dimer modulation in TCNQ radical anion salts
We report a liquescent 7,7,8,8-tetracyanoquinodimethane radical anion (TCNQ˙<sup>-</sup>) salt with an <i>N</i>,<i>N</i>'-di-<i>n</i>-octylimidazolium ion that exhibits unprecedented three-stage switching of magnetic and NIR-II absorption properties upon thermal stimulation. This behavior originates from stepwise transformations between co-facial and slipped-stacking π-dimers and monomeric TCNQ˙<sup>-</sup> species.
