In general, if the atoms that make up the ring contain heteroatoms, such rings become heterocycles, and organic compounds containing heterocycles are called heterocyclic compounds. An article called Induction, fixation and recovery of self-organized helical superstructures in achiral liquid crystalline polymer, published in 2021, which mentions a compound: 4221-99-2, Name is (S)-Butan-2-ol, Molecular C4H10O, Computed Properties of C4H10O.
The fixation, storage and self-recovery of chiral information in superstructures constructed by weak noncovalent bonds remain a big challenge in nature. Here, we describe a novel self-assembled system where the mol. chirality can be transferred and further stored into a helical superstructure. Based on achiral liquid crystalline polymers (LCPs), the twist between azobenzene (Azo) units in polymer side chains can be switched by the configuration or alkyl chain length of the introduced chiral dopant. Furthermore, the crosslinking strategy of polymer side chains was adopted to allow permanent memory of the induced helical superstructure after complete removal of the chiral dopant. Although the helical superstructure was temporarily destroyed by UV light irradiation, the stored chiral information enabled self-recovery of the previous helical chirality, without the need for any pre-existing chiral source. The chiral switching in the absence of chiral source is unprecedented and opens a new window for the design and application of chiral materials.
