Photoreactivity of Ruthenium Polypyridyl Complexes with H2S Donor GYY4137

Four ruthenium(II) polypyridyl complexes bearing the H2S-releasing donor GYY4137 were synthesized and characterized. Their photochemical reactivity was investigated, revealing a two-step ligand photodissociation process with long-lived intermediates. The dataset includes measurements of photochemical quantum yields and results from density functional theory calculations.

Use Cases

• Modeling photodissociation kinetics based on the described two-step reaction mechanism.
• Predicting photoproduct identity based on the ancillary diimine ligand structure.
• Correlating quantum yields with ligand planarity as described in the study.
• Designing new photoactivated H2S donors based on insights into the ligand ejection process.

Strengths

• Includes data from four distinct synthesized complexes with different diimine ligands.
• Characterization methods include NMR spectroscopy and X-ray crystallography.
• Combines experimental photochemical quantum yield measurements with density functional theory calculations.

Limitations

• Row count is unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• The dataset is very small (40.9 KB), indicating limited scope.
