A piezoelectric element includes: a piezoelectric body having a first surface and a second surface that are different from each other; a first electrode provided at the first surface; and a second electrode provided at the second surface. The piezoelectric body contains a helical chiral polymer crystal having an orientation axis as a crystal axis, the orientation axis is uniaxially oriented in a manner of intersecting both the first surface and the second surface, and a degree of orientation of the orientation axis in the piezoelectric body is 0.80 or more.

A kind of circularly polarized chiral organic fluorescent light emitting material and its preparation method and application belong to the technical field of design, preparation and application of chiral polymer functional materials.The chiral binaphthyl compound R / S-2 prepared as chiral monomer is coupled with the monomer of fluorenyl chromophore group with single bond, double bond and triple bond connector to prepare three intrinsic chiral polymer functional fluorescent light emitting materials R / S-P1, R / S-P2 and R / S-P3 with different conjugated main chain conformations by Suzuki, Heck and Sonogashira coupling polymerization reaction, and their photophysical properties and chiral luminescence performance in thin film state are studied.The experiment proves that the product prepared by the application embodies the controllable photophysical properties in test, and has certain circular dichroism and circularly polarized luminescence properties, indicating that it is expected to be applied in the field of chiral solid-state display material and optoelectronic device.
