Chiral switch aujourd'hui
WebThus, by the end of the 1990s and the beginning of 2000s, the “chiral switch” process had become increasingly prominent, this term referring to the replacement of a chiral drug used in the form of a racemate with its eutomer; a change in the chirality status being the most important requirement for a chiral switch. The chiral switch phenomenon WebThe switching of supramolecular chirality in the forms of on/off, amplification/weakening and chirality inversion is shown. Additionally, the design of chiroptical switchable systems for chiral logic gates, data …
