Abstract:A liquescent salt consisting of a 7,7,8,8‐tetracyanquinodimethane (TCNQ) radical anion and a tetra‐n‐decylammonium ion, 1+•TCNQ•−, exhibits rapid changes in the short‐wave infrared (SWIR) light transparency at 1000–1400 nm upon the application of a one‐shot needlestick‐stimulus. Radical anion salt 1+•TCNQ•− transforms from a blue solid to a green liquid at 90 °C without decomposition under aerated conditions, and remains in the liquid state upon cooling to 70 °C. After applying pressure with a needlestick on a… Show more
