Tunable Piezochromic Luminescence via Isomer Control in N,N'-Azotriazole Energetic molecules

Key Points

• This research aims to explore how isomer variations in N,N'-azotriazole affect luminescent properties under pressure.
• Investigated isomeric variants of N,N'-azotriazole energetic materials
• Measured pressure-dependent luminescence shifts
• Compared blue and red shifts in different isomers
• 4,4'-Azo-1,2,4-triazole shows blue-shifted luminescence under pressure
• 1,1'-azo-1,2,3-triazole maintains red-shifts under similar conditions
• Diverse luminescent behaviors highlight the role of isomer control in energetic materials
