Abstract

Graphical abstract: Highlights: First LiHSO4 selective ion pair receptor based on tolan structure. Ion pair selectivity for Li + over Na + and K + . Solid–liquid extraction (SLE) for Li + from a mixture of solid LiCl, NaCl, and KCl. Extraction and sensing (fluorescence quenching) together for Li + (LiHSO4 ). Abstract: A new tolan derivative was synthesized as a selective ion pair receptor for LiHSO4 . The observed ion pair selectivity was accomplished by introducing aza-12-crown-4, which is size-selective for Li + . The ion pair receptor can function as an extractor and fluorescent indicator for LiHSO4 .
