Abstract
Two chiral copper(II)-based receptors—[CuRRL]2+ and [CuSSL]2+—in conjuction with the fluorescent indicator coumarin 343 were used to establish an enantioselective indicator displacement assay (eIDA) for the determination of the enantiomeric composition of chiral carboxylates such as ibuprofen, naproxen and atorvastatin.
