Fluorenyl cyano indanone non-conjugated polymer receptor and preparation method thereof

The invention relates to a fluorenyl cyano indanone non-conjugated polymer receptor and a preparation method thereof. The invention relates to a conjugated polymer based on thiophene and benzothiadiazole and a preparation method thereof. According to the invention, a non-trapezoidal condensed ring micromolecule monomer is designed and synthesized by using fluorene and cyano indanone structural units, and then the non-conjugated polymer receptor with good solubility is synthesized by a Stille copolymerization method. According to the invention, non-trapezoidal fused ring small molecule receptors are bridged through a non-conjugated alkyl chain to form a main chain non-conjugated polymer receptor, the main chain non-conjugated polymer receptor has wide and strong absorption in a visible-near infrared region, and a flexible side chain can provide good solubility for a material. The effective intermolecular charge transfer can occur between the polymer and a donor, and the polymer has good physicochemical propert
