摘要：
A new chiral sensor based on an N,N-dioxide nickel(II) complex was prepared, which could visually recognize a series of chiral alpha-hydroxycarboxylic acid enantiomers by coordination and self-assembly forming into nanospheres or nanofibers. With the help of various techniques, the morphology structures of the colloid or suspension were obtained and the counterion-displacement assays were also confirmed. In addition, this metal complex could act as a highly enantioselective fluorescence sensor to recognize N-Boc-amino acids and chiral alpha-hydroxycarboxylic acids.
