Abstract: The invention provides a ZnO-nanorod molecular-imprinted fluorescent sensor and a preparation method and application thereof and belongs to the technical field of environmental functional material preparation. The method comprises the steps of dispersing zinc acetate into methanol firstly, refluxing until zinc acetate is dissolved, then, pouring a methanol solution of potassium hydroxide into the reaction, vigorously stirring, carrying out refluxing reaction for a plurality of days, repeatedly washing centrifugally after the reaction is ended, so as to obtain ZnO nanorods, baking for later use, carrying out vinyl modification on the obtained ZnO nanorods by using 3-(methacryloyloxy)propyl trimethoxysilane, then, synthesizing a ZnO-nanorod fluorescent molecular-imprinted polymer, which takes p-nitrophenol as template molecules, methacrylic acid as functional monomers, ZnO-KH570 as a support, ethylene glycol di(methacrylate) as a cross-linking agent, 2,2-azodiisobutyronitrile as an initiator and acetonitrile as a solvent, by using a precipitation polymerization method, and applying the ZnO-nanorod fluorescent molecular-imprinted polymer to the optical detection on p-nitrophenol. The prepared fluorescent molecular-imprinted polymer has very good optical and pH stability and has the capability of selectively identifying p-nitrophenol.
