Figure 4. (A) Graphical representation of the construction of chiral metallacage P-11o form the chiral diarylethene ligand P-8o. (B) Photoisomerization between the two isomers P-11o and (R, R)-11c. (C) The CD spectral changes of P-11o under UV irradiation. (D) Schematic illustration of the non-destructive “writing”, “erasing” and “reading” with chiral metallacycles.
