Chiral photoswitches based on dithienylethenes have attracted extensive attention due to their unique chirality and optical activities, endowing them with potential applications in a multitude of fields. Herein, we present a new dithienylethene-based supramolecular chiroptical switch system driven by phosphate coordination. In the open-ring form, a mesocate structure (circular dichroism (CD) silent) is observed. Upon photoisomerization to the closed-ring form, the system undergoes a structural transition to a chiral helicate, exhibiting turn-on CD and enabling reversible chiroptical switching.

Stereoisomerism
Isomers are different chemical species that have the same chemical formula.
Transition metal complexes often exist as geometric isomers, in which the same atoms are connected through the same types of bonds but with differences in their orientation in space. Coordination complexes with two different ligands in the cis and trans positions from a ligand of interest form isomers. For example, the octahedral [Co(NH3)4Cl2]+ ion has two isomers (Figure 1) In the cis...
