Visual enantioselective probe based on metal organic framework incorporating quantum dots

A new method was developed for visual enantioselective sensing based on quantum dot (QD) doped metal organic framework (MOF), which firstly combined the chiral selectivity of MOF and sensing of QD quenching. A simple synthesis procedure with much less reaction time is developed, with small and homogenously-sized QD@MOF particles obtained, as well as a cheaper dispersant used. The proposed sensing method is proved to be direct, convenient, and visual. Qualification and preliminary quantification of enantiomers can be accomplished in a visual fashion. The proposed method also demonstrates practical utility, and it is expected to be expanded to enantioselective determination of other enantiomers. (C) 2013 Elsevier B.V. All rights reserved.
