Synthesized Tetracyclic Pyranonaphthoquinone Compounds with Fluorescent Sensor Properties

A set of synthesized succinimide-embedded tetracyclic pyranonaphthoquinone compounds, created via a Pd(II)-catalyzed C–H activation and O‑annulation method. The data includes one compound demonstrating high sensitivity and selectivity as a fluorescent chemosensor for Fe³⁺ ions, with a detection limit of 30.07 × 10⁻⁹ M. The dataset was authored by Eswaran Kamaraj and last updated on figshare in April 2026.

Use Cases

• Training models for predicting compound properties based on synthetic pathways described.
• Analyzing structure-activity relationships for metal ion sensing based on the described fluorescence properties.
• Screening for novel chemosensor candidates based on the succinimide-integrated tetracyclic motif.
• Benchmarking synthetic methodologies for [5 + 1] cycloaddition reactions as described.

Strengths

• Includes a specific, quantified performance metric: a compound with a Fe³⁺ ion detection limit of 30.07 × 10⁻⁹ M.
• Describes a specific synthetic methodology: Pd(II)-catalyzed cascade C–H activation/O‑annulation.
• File format is CIF, a standard for crystallographic information, suggesting structured chemical data.

Limitations

• Row count is unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• Description metadata is limited; actual data quality requires manual inspection after download.
