WebJul 1, 2001 · The other approach to chiroptical photoswitches is employment of truly enantiomeric molecules that are addressed by circularly polarized light. Irradiation of compounds such as 3 and 4 ( Fig. 1; Ref. 3 ), which are enantiomers, will obviously result in an equal population of the two. WebThe 2016 Nobel Prize in Chemistry has been awarded to the work on the design and synthesis of tiny molecular machines. How to utilize the cooperative action of the molecular motors to drive the collective motion of microscale objects remains a grand challenge.
