“…Then, layers are linked by weak C–H···Br interactions (4.059 Å) in a zigzag pattern along the c- axis (Figure d). When single crystal A1 was subjected by- external stress on (10–1) or (001) face, π···π interactions acted as the structure buffer to release the produced strains, which were accompanied by the expansion of interactions in the outer arc and the contraction of interactions in the inner arc (Figure d,g) . Besides, C–H···Br interactions on the (10–1) face and C–H···C and C–H···O interactions on the (001) face could hinder molecular relative slippage to avoid plastic deformation.…”

The application of organic molecular crystals is currently limited by their poor mechanical properties. Crystal engineering could be an effective approach to design and modify organic crystals with different structures and diverse mechanical and other properties. In this work, we synthesized a series of N-salicylideneaniline derivatives (Schiff Bases) with different substituents, which exhibited various mechano-responsive behaviors like two-dimensional (2D) elasticity, plasticity, twisting, and fracture. Besides that, distinct fluorescence emission behaviors were observed due to their different crystal structures. Mechanofluorochromic phenomena were demonstrated in flexible crystals where a reversible fluorescence peak shift occurred in elastic crystals and a red shift appeared in plastic crystals. Organic crystals with mechano-sensitive behaviors and fluorescence properties hold great potential in flexible optoelectronic materials, such as sensors and actuators.

Integrating 2D elasticity and elastoplasticity into a multi-stimuli-responsive crystal through phase transitions

Abstract: Practical applications of flexible crystals are often limited due to their monotonous property. In this study, multi-stimuli-responsive crystals of isonicotinamide (INA), which astoundingly respond to all mechanical force, heat and...
