Red-fluorescence under UV and green-SHG under NIR dual-mode emission in a yellow crystal of a 1,2,5-thiadiazole derivative
A yellow chiral crystal of a 1,2,5-thiadiazole-substituted pyrazine exhibited red excimer-like emission above 600 nm with a Stokes shift exceeding 200 nm under UV, which also enabled green second harmonic generation (SHG) under near-infrared irradiation.
