Squaraine Dye Properties for Amine Gas Sensing

Parker A. E. Mikkelsen's dataset, last updated April 2026, investigates the structure-property relationships of the dye molecule bis(1,3,5-trihydroxyphenyl) squaraine (SQPH). The data includes single-crystal X-ray diffraction analysis, UV–visible spectroscopy, acid–base titrations, and electrochemistry results. It also contains information on ink formulations and film coatings for gas-sensing applications.

Use Cases

• Modeling structure-property relationships based on X-ray diffraction and spectroscopy data.
• Developing optical gas sensors based on the described color change and decolorization upon amine exposure.
• Engineering ink formulations for sensor films based on the high-throughput coating technique described.
• Analyzing J-aggregate equilibria and acid-base progression based on the optical features mapped in the study.

Strengths

• Data includes multiple analytical techniques: X-ray diffraction, UV–visible spectroscopy, acid–base titrations, and electrochemistry.
• The dataset is associated with a specific, well-described chemical compound (SQPH).
• File size is 302.0 KB, indicating a focused and manageable dataset.

Limitations

• Row count and column-level documentation are unknown, limiting suitability assessment.
• The dataset's 302.0 KB size suggests a very limited scope, likely containing only core experimental results.
