A compound based on 2,2′-bis(indolyl)methane containing nitro group was studied as a new anion receptor. It could recognize selectively F − by an increasing fluorescence signal and a visible color change from colorless to blue. The introduction of nitro group induced the spectral dual-function related to the deprotonation of N–H protons. [ABSTRACT FROM AUTHOR]
