主 题：channel luminescence locking
摘 要：Organic mechanoluminescence materials,featuring dual emission and ultralong phosphorescence characteristics,exhibit significant potential for applications in real-time stress sensing,pressure-sensitive lighting,advanced security marking techniques,and material breakage ***,due to immature molecular design strategies and unclear luminescence mechanisms,these materials remain rarely *** this study,we propose a valuable molecular design strategy to achieve dual-channel *** introducing the arylphosphine oxide group into a highly twisted molecular framework,enhanced intra-and intermolecular interactions could be achieved within rigid structures,leading to dual-channel mechanoluminescence with greatly promoted ultralong *** investigations reveal the substantial boosting effect of intra-and intermolecular interactions on mechanoluminescence and ultralong phosphorescence properties by locking the highly twisted molecular *** work provides a concise and guiding route to develop novel smart responsive luminescence materials for widespread applications in material science.
