Dynamic Control of Racemization Rate through E−Z Photoisomerization of Azobenzene and Subsequent Partial Photoresolution under Circular Polarized Light
摘要:
We have synthesized bicyclic azobenzene dimers that possess enantiomers whose racemization rates could be controlled reversibly through E-Z photoisomerization of the azobenzene units. Upon alternating the exposure to r- and l-CPL, we were able to repeatedly perform partial enrichment of (S)- and (R)- enantiomers, respectively.
