Pressure-Induced Emission Enhancement in 2-(anthracen-9-yl)-9Hthioxanthen-9-one Crystals with π-π Stacked Thioxanthone Dimers

Key Points

• This research aims to investigate how pressure affects the fluorescence emission properties of TXAN crystals.
• Analyzed the fluorescence of TXAN under various pressure levels.
• Studied the linear piezochromic behavior resulting from pressurization.
• Utilized high-pressure techniques to measure emission peak shifts.
• TXAN showed blue-violet fluorescence at ambient pressure.
• Under increased pressure, a continuous redshift of the emission peak was observed.
• Linear piezochromic behavior was confirmed across pressure ranges.
