Abstract

The invention provides polydiacetylene with a spiral structure as well as a preparation method and an application of polydiacetylene. According to the preparation method of polydiacetylene, polydiacetylene with the spiral structure is obtained from a benzaldehyde diacetylene film by irradiating with super-chiral light for 25-40 min, wherein the ultra-chiral light is formed by steps as follows: a laser beam emitted by a 325 nm helium-cadmium laser is split into two opposing laser beams by an ultraviolet beam splitter, the two opposite laser beams pass through a Glan prism and a 1 / 4 polaroid respectively, and two opposite circularly polarized beams are obtained, and standing waves, namely, the super-chiral light, are formed by the two opposite laser beams in the interference region. Resultsshow that polydiacetylene obtained from the benzaldehyde diacetylene film irradiated by the super-chiral light has better spiral structure and stronger chirality, and has stronger interaction and is more sensitive in detection when used for detecting amino acids.

Description

technical field

[0001] The invention relates to superchiral optical path technology, in particular to a polydiacetylene with helical structure and its preparation method and application. Background technique

[0002] Chirality was proposed by the famous scientist Lord Kelvin in 1893, and it is often used in various interdisciplinary fields to express the property that an object and its mirror image cannot overlap. Compounds with chiral properties generally exist in chemistry, biology, medicine, materials and other disciplines and interdisciplinary subjects, and play a very important role, such as the various units that constitute organic life, such as amino acids are in L-conformation, DNA is Right-handed conformation. Chirality exists widely, and usually exists in nature with a specific chirality, and circularly polarized light originating from the formation of the universe is often used as an external physical method to prepare and regulate helical polymer photonic materi...
