A stilbene-based halochromic dye was synthesized, which possesses the effect of intramolecular color matching. By dyeing cotton fabric with the synthesized dye, a textile sensor material was prepared to visually monitor the acidity of the biologically significant pH range (4.5–8.0). The sensitivity...
