Carbon-tetrel bonds: cooperative existence and disappearance in elastically bendable fluorescent organic single crystals by operating within the hierarchy of non-covalent interactions

Key Points

• Mechanical properties of fluorescent organic crystals are enhanced using carbon-tetrel bonds, showing promising flexibility.
• DFT calculations demonstrate how cooperativity in these bonds influences the material's performance and resilience.
• The analysis of these bonds highlights the role of non-covalent interactions in defining the mechanical characteristics.
• These findings may enable the design of advanced materials with improved structural integrity and functionality.
