A new chromogenic indoaniline-thiourea-based sensor was designed to recognize anions in an organic solvent through complementary intermolecular hydrogen bonding. Complexed anions cause significant disturbance to the intramolecular hydrogen-bonded structure of the sensor, which then induces color and UV-vis spectral changes. This sensor allows for selective colorimetric detection of tetrahedral oxoanions (HSO4- and H2PO4-).
