Application of chiral spirofluorene isomers to electronic components with chiral association function

The invention relates to application of chiral spirofluorene isomers in electronic components with a chiral association function. The chiral spirofluorene isomers comprise an R-type isomer and an S-type isomer as shown in a formula I. It is found for the first time that the chiral spirofluorene isomers as shown in the formula I can be applied to the electronic components with the chiral association function. The application lie in the fact that the R/S chiral spirofluorene structure enantiomer has a deflection surface of +/-90 DEG C and can better induce the chirality of a second-level structure and a third-level structure in the solid film, so a functional film capable of generating circularly polarized light is obtained, and a circularly polarized light device is prepared.
