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 monitoring. However, due to immature molecular design strategies and unclear luminescence mechanisms, these materials remain rarely reported. In this study, we propose a valuable molecular design strategy to achieve dual-channel mechano-phosphorescence. By 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 phosphorescence. Further investigations reveal the substantial boosting effect of intra- and intermolecular interactions on mechanoluminescence and ultralong phosphorescence properties by locking the highly twisted molecular skeleton. This work provides a concise and guiding route to develop novel smart responsive luminescence materials for widespread applications in material science.

Hierarchical organization is prevalent in nature, yet the artificial construction of hierarchical materials featuring asymmetric structures remains a big challenge. Herein, we report a stress-induced self-assembly strategy for the synthesis of hierarchically twisted stripe arrays (HTSAs) with mesoporous structures. A soft and thin mesostructured film assembled by micelles and TiO oligomers is the prerequisite.

Strategies to acquire high-efficiency luminogens that emit in the second near-infrared (NIR-II, 1000-1700 nm) range are still rare due to the impediment of the energy gap law. Herein, a feasible strategy is pioneered by installing large-volume encumbrances in a confined space to intensify the repulsive interactions arising from overlapping electron densities. The experimental results, including smaller coordinate displacement, reduced reorganization energy, and suppressed internal conversion, demonstrate that the repulsive interactions assist in the inhibition of radiationless deactivation.

Background: Botrytis cinerea is one of the most serious plant diseases and severely threatens agricultural production. The rapidly intensifying resistance makes most commercial chemical fungicides lose control efficacy. Developing new fungicides with novel structures and modes of action is an effective measure to solve this problem.

Article Synopsis
- Single crystals that lack translational symmetry have been observed in different materials, particularly in polymers where unique structures like twisted crystals and non-flat single crystals appear.
- Researchers have discovered scrolled single crystals of poly(L-lactic acid) (PLLA), a biodegradable polymer, which differ from the typical flat crystals formed in solution.
- The scrolled structure of PLLA crystals is influenced by factors such as the polymer's molecular weight and the presence of polymer chain ends, suggesting a novel mechanism for disrupting translational symmetry in the growth of polymer single crystals.
