Luminescent rhenium(i) perfluorobiphenyl complexes as site-specific labels for peptides to afford photofunctional bioconjugates†
Abstract
We report herein new luminescent rhenium(I) perfluorobiphenyl complexes that reacted specifically with the cysteine residue of the π-clamp sequence (FCPF) to afford novel peptide-based imaging reagents, photosensitisers for singlet oxygen and enzyme sensors.
