文摘
Two rhodamine-derived chemosensors for cysteine optical sensing were reported.
Up-conversion nanocrystals were prepared and used as excitation host.
Efficient energy transfer between nanocrystals and chemosensors was confirmed.
A simple recognition mechanism with binding stoichiometry of 1:1 was observed.
Good selectivity and linear sensing behavior were obtained.
