- 01HM98233B4QB27KMM7HZ3YSQB 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], while the solid-state synthesis of single-crystalline organic polymers, having functional properties, remains an attractive and developing research area in polymer chemistry [2]. First, we present an intriguing example of photomechanical molecular single crystals of a newly synthesized organoboron containing Lewis acid-base molecular adduct, which - under UV light - exhibit controllable rapid bending-shape recovery, delamination, violent splitting/fragmenting-jumping, and expanding features [3]. Detailed structural investigation by single-crystal X-ray diffraction and 1H NMR spectroscopy reveals that the photosalient behavior of these single crystals is driven by a single-crystal-to-single-crystal (SCSC) [2+2] cycloaddition reaction, while they display short-lived room temperature phosphorescence (RTP). Second, we demonstrate three new stoichiometrically different Lewis acid-base molecular organoboron adducts, which exhibit rapid photosalient effects (ballistic splitting, moving, and jumping) under both ultraviolet (UV) and visible/sun light associated with quantitative SCSC [2+2] cycloaddition of preorganized olefins, while they display visible lightpromoted dynamic green RTP [4]. Time-dependent structural mapping of intermediate photoproducts during fast SCSC [2+2] photoreaction, by X-ray photodiffraction, reveals a rationale for the origin of these photodynamic motions associated with rapid topochemical transformations. Third, we describe another example of SCSC rapid photosynthesis of two structurally different linear organoboron polymers, driven by sustainable visible/sun light, obtained from the same monomer molecule, which crystallizes in two solid-state forms with different structural topologies. The guest solvent-free crystals of the first monomer undergo topochemical photopolymerization via an unusual olefin-naphthyl ring [2+2] cyclization to yield the single crystalline [3]-ladderane polymer, accompanied by instantaneous and violent macroscopic mechanical motions (such as bending-reshaping, and popping effects). In contrast, visible light-harvesting single crystals of the second monomerquantitatively polymerize in a SCSC fashion owing to rapid [2+2] cycloaddition reaction among olefin double bonds, while showing photodynamic popping effects in response to visible light. Both monomer crystals and their single crystalline polymers feature green emissive and short-lived room temperature phosphorescence.".
