Abstract

New coumarin-based chiral thiourea sensor 1 was found to be an enantioselective fluorescent chemosensor for N-Boc-protected proline. The chiral sensor shows lower background fluorescence, and higher fluorescence enhancement with 18 nm blue shifts. Job plot analysis result indicates that sensor 1 can form a 1 : 1 stoichiometric complex and it could be used as a fluorescence sensor for the determination of enantiomer composition of N-Boc-protected proline.
