(E)-3-(meso-Octamethylcalix[4]pyrrol-2-yl)propenal: a versatile precursor for calix[4]pyrrole-based chromogenic anion sensors
摘要:
The synthesis of (E)-3-(meso-octamethylcalix[4]pyrrol-2-yl)propenal and its use in Knoevenagel reactions are described. The resulting compounds display sharp changes in color in the presence of fluoride, acetate, and dihydrogen phosphate anions. (C) 2010 Elsevier Ltd. All rights reserved.
