Organic Persistent Room Temperature Phosphorescence Enabled by Carbazole Impurity

A dataset from a study on metal-free organic phosphors for persistent room-temperature phosphorescence. It likely contains photophysical property data for a series of halobenzonitrile–carbazole compounds, including quantum yields and excited state lifetimes. The dataset was authored by Alexander C. Brannan and last updated on figshare in June 2026.

Use Cases

• Training models to predict phosphorescence quantum yield based on molecular substituents and geometry.
• Analyzing the relationship between crystal lattice geometry and excited state lifetime for organic phosphors.
• Classifying compounds as exhibiting persistent room-temperature phosphorescence or thermally activated delayed fluorescence based on synthesis origin.

Strengths

• Includes specific photophysical metrics such as a quantum yield of up to 22% and an excited state lifetime of up to 0.22 seconds.
• Compounds were synthesized via a defined one-pot nucleophilic substitution protocol, suggesting controlled experimental conditions.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• The dataset is a 7.1 MB DOCX file, which may require parsing to extract structured data.
