A series of halobenzonitrile–carbazoles demonstrates efficient persistent room-temperature phosphorescence with a quantum yield of up to 22% and an excited state lifetime of up to 0.22 seconds. Compounds from laboratory-synthesized carbazole exhibit thermally activated delayed fluorescence with millisecond-range lifetimes. Alexander C. Brannan published this research on figshare in June 2026.
Use Cases
- Analyze the relationship between molecular geometry and luminescence properties based on tilt/twist of carbazole moieties.
- Compare photophysical performance between commercially sourced and laboratory-synthesized carbazole compounds.
- Investigate the role of mixed locally excited and charge transfer states in luminescence origin.
Strengths
- Specific photophysical metrics are provided, including a quantum yield of up to 22% and an excited state lifetime of up to 0.22 s.
- The description details a clear experimental protocol involving a one-pot nucleophilic substitution.
- The dataset is published under a CC-BY-4.0 license, facilitating reuse.
Limitations
- The dataset is a single PDF file of 252.7 KB, indicating a very limited scope likely focused on a specific experimental series.
- Column-level documentation is absent; field semantics must be inferred after download.
- Row count is unknown, which may limit suitability assessment.
Provenance
