It greatly expands the substrate scope of the corresponding BINOL\u2010based sensor. A dramatic solvent effect was observed for the reaction of the amines with compound (<jats:italic>S<\/jats:italic>)\u2010<jats:bold>2<\/jats:bold>. In DMF, cleavage of the perfluoroalkyl group of compound (<jats:italic>S<\/jats:italic>)\u2010<jats:bold>2<\/jats:bold> to form amides was observed but not in other solvents, such as methylene chloride, chloroform, THF, hexane, and perfluorohexane. Thus, the addition of another solvent, such as THF, can effectively quench the reaction of compound (<jats:italic>S<\/jats:italic>)\u2010<jats:bold>2<\/jats:bold> with amines in DMF to allow stable fluorescent measurement. This is the first example that the formation of strong amide bonds under very mild conditions is used for the enantioselective recognition of chiral amines. The mechanism of the reaction of compound (<jats:italic>S<\/jats:italic>)\u2010<jats:bold>2<\/jats:bold> with chiral amines is investigated by using various analytical methods including mass spectrometry as well as NMR and UV\/Vis absorption spectroscopy.<\/jats:p>","DOI":"10.1002\/chem.201600238","type":"journal-article","created":{"date-parts":[[2016,4,10]],"date-time":"2016-04-10T14:52:41Z","timestamp":1460299961000},"page":"7255-7261","source":"Crossref","is-referenced-by-count":15,"title":["Highly
