A simple one-bath strategy has been developed to synthesize a novel CdTe@SiO_2@MIP(molecularly imprinted and silica-functionalized CdTe quantum dots,MISFQDs),in which a silica shell was coated on the surface of CdTe quantum dots (CdTe@SiO_2 QDs) and then a polymer for selective recognition of 4-chlorophenol(4-CP) was constructed on the surface of CdTe@SiO_2 QDs using mercaptoacetic acid as stabilizer,3-aminopropyl-trimethoxysilane(APTES) as functional monomers and tetraethoxysilane(TEOS) as crosslink agent.The structures of CdTe@SiO_2@MIP were analyzed by ultraviolet-visible absorption. Fluorescence,FT-IR spectrum and powder X-ray diffraction.The application and characterization of the CdTe@SiO_2@MIP were investigated by experiments.All results indicated that the CdTe@SiO_2@MIP can selectively recognize 4-chlorophenol.
