- 01HM8X5ZGPTAV7K07RCYS3QW7H abstract "Photoluminescent molecular crystals, integrated with the ability to transform light energy into macroscopic mechanical motions, are a promising choice of materials for both actuating and photonic devices [1]. However, such dynamic photomechanical effects, based on molecular organoboron compounds as well as phosphorescent crystalline materials, are not yet known. Here we present an intriguing example of photomechanical molecular single crystals of a newly synthesized organoboron containing Lewis acid-base molecular adduct (BN1, substituted triphenylboroxine and 1,2-di(4-pyridyl)ethylene) having a capsule shape molecular geometry [2]. The single crystals of BN1 under UV light exhibit controllable rapid bending-shape recovery, delamination, violent splitting/fragmenting-jumping, and expanding features (Fig. 1). The detailed structural investigation by single-crystal X-ray diffraction and 1 H NMR spectroscopy reveals that the photosalient behavior of the BN1 single crystals is driven by a crystal-to-crystal [2+2] cycloaddition reaction, supported by four donor-acceptor type BĸN bonds. The instant photomechanical reaction in the BN1 crystals occurs under UV on the account of sudden release of stress associated with the strained molecular geometry, significant solid-state molecular movements (major supramolecular change), and cleavage of half intermolecular BĸN linkages to result in a complete photodimerized single-crystalline product via the existence of two other intermediate photoproducts. In addition, a solidstate photoluminescence study indicates that single crystals of BN1 display short-lived room temperature phosphorescence, while the light-induced topochemical reaction is accompanied by the enhancement of their phosphorescence intensity to yield the [2+2] photocyclized crystals. Interestingly, the molecular crystals of the final photoproduct polymerize at ambient conditions when recrystallized from the solution forming a 2D supramolecular crystalline polymer stabilized by the retention of all BĸN coordination modes.".
