Reversible low-light induced photoswitching of crowned spiropyran-DO3A complexed with gadolinium(III) ions. [PDF]

, 2012
Photoswitchable spiropyran has been conjugated to the crowned ring system DO3A, which improves its solubility in dipolar and polar media and stabilizes the merocyanine isomer. Adding the lanthanide ion gadolinium(III) to the macrocyclic ring system leads
