Negative Solvatochromism of an Anionic Thiazole‐Based Dye

Abstract

Keep it small, flat, and easy: The synthesis of an unconventional strong solvatochromic dye is presented. The solvatochromic and NMR behavior of the anionic chromophore was characterized and the compound might be used as a sensor. The thiazol-4-olate donor group is derived from the oxyluciferin of fireflies and strongly influences the electronic properties of the dye.
