The effective removal of trace metal contaminants from reaction mixtures is an important but challenging task. To address this challenge, we are developing a new metal sequestering precipiton that would selectively precipitate upon metal-to-precipiton binding. The isomerization kinetics of a precipiton that is tethered to a ruthenium sensitizer has been compared to an untethered precipiton. The tethered precipiton was observed to isomerize much faster than the untethered example. The scope, synthesis, and isomerization kinetics of this model system will be discussed.
