A BINOL-based chiral polyammonium receptor for highly enantioselective recognition and fluorescence sensing of (S,S)-tartaric acid in aqueous solution†
Abstract
A chiral ditopic polyammonium receptor featuring two [9]aneN3 moieties separated by a (S)-BINOL linker is able to selectively bind and sense in water (S,S)-tartaric acid over its (R,R)/meso forms.
