WebDec 25, 2024 · The precise adjustment of handedness of helical architectures is important to regulate their functions. Macroscopic chirality inversion has been achieved in organic supramolecular systems by pH, metal ions, solvents, chiral and non-chiral additives, temperature, and light, but rarely in coordination polymers (CPs). In particular, salt … WebA chiral switch is a chiral drug that has already approved as racemate but has been re-developed as a single enantiomer. [1] [2] The term chiral switching was introduced by Agranat and Caner in 1999 [3] to describe the development of single enantiomers from racemate drugs. For example, levofloxacin is a chiral switch of racemic ofloxacin.
