The invention discloses synthesis for chiral polyester containing binaphthyl. A binaphthyl compound is a common atropisomer compound with a C3 chiral axis. The axis of a binaphthyl structure is in an asymmetrical, multifunctional and stable chiral form, so that molecules and copolymers constructed by binaphthyl have superior structures and properties and wide application prospects in the field of materials. The patent is developed mainly around the synthesis of novel chiral polyester containing binaphthyl. A method for preparing the chiral polyester comprises the following steps of: synthesizing binaphthol or dinaphthyline by taking 2-naphthol or 2-naphthylamine as a raw material, and splitting to obtain chiral binaphthol or dinaphthyline; making dinaphthyline react with halohydrinare to obtain diol containing dinaphthalene radial, and react with the diacid to obtain chiral polyester; and making naphthidine react with chloride acyl chloride, hydrolyzing to obtain diol containing binaphthyl, and reacting with diacid to obtain chiral polyester containing binaphthyl. In the preparation of the chiral polyester, diol or diacid containing binaphthyl is prepared firstly, and then the chiral polyester is prepared by reacting. At last, the prepared chiral polyester is applied to molecular recognition.
