characterized for effective fluoride and acetate anion sensing. The new indole-based system has a highly flat rigid structure with a large pi system, and exhibits high binding affinity and sensitivity for acetate and fluoride anions. Receptors 6 and 7 give abundant and unique spectral features in dimethyl sulfoxide (DMSO). Both fluoride and acetate anions cause a bathochromic shift of the absorption peaks
