Anion sensor based on the indoaniline: Thiourea system


, : Anion sensor based on the indoaniline: Thiourea system. Tetrahedron Letters 43(40): 7273-7276, 30 September

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-).

The activity of the predacious mite P. persimUis Athias-Henriot and its prey, T. urticae (Koch), was studied at several humidity levels. The prey, but not the predator, continuously avoided high humidities. Both species were more active in low hum...
