This research aims to explore a method for the controlled release of metal ions using near-IR light as a trigger.
Developed a ligand containing a dithioethenyl moiety for metal ion caging.
Employed low-energy red/near-IR light to cleave the ligand, reducing metal-ion affinity.
Investigated the role of singlet oxygen generated during photosensitization.
The dithioethenyl ligand effectively cleaved under near-IR light, enabling controlled release of metal ions.
Singlet oxygen generation confirmed as a key mechanism for the cleavage process.
The approach demonstrated several tunable factors, enhancing the efficacy of ion caging.
