Abstract

Dynamic photoactuating crystals are making waves for their ability to transform industries, offering groundbreaking possibilities in fields such as medical technology, robotics, and flexible electronics. These crystals respond to light, enabling innovations such as smart devices, artificial muscles, molecular machines, sensors, and microrobots, heralding a new era of highly adaptive and efficient technologies. Herein, we report two iso-structural metal–organic crystals [Cd(quin)₂(4-nvp)₂] and [Zn(quin)₂(4-nvp)₂] [Hquin = quinoline-2-carboxylic acid and 4-nvp = 4-(1-naphthylvinyl)pyridine] based on Cd(II) and Zn(II) ions respectively, that undergo solid-state photochemical [2 + 2] cycloaddition reaction accompanied by photosalient (PS) effect, wherein both the crystals show popping, swelling, and splitting upon UV irradiation, explicitly probed by nanoindentation studies. Thus, these findings may pave the way for the fabrication of photoactuating smart materials.

光凸等结构金属-有机晶体结构-纳米力学性能的相关性研究

动态光致晶体因其改变行业的能力而掀起波澜，在医疗技术、机器人技术和柔性电子等领域提供了突破性的可能性。这些晶体对光作出反应，使智能设备、人造肌肉、分子机器、传感器和微型机器人等创新成为可能，预示着一个高度自适应和高效技术的新时代。在此，我们报道了两个基于Cd（II）和Zn（II）离子的同结构金属有机晶体[Cd(quin)2(4-nvp)2]和[Zn(quin)2(4-nvp)2] [Hquin =喹啉-2-羧酸和4-nvp = 4-（1-萘基乙烯基）吡啶]，它们分别进行了固态光化学[2 + 2]环加成反应并伴有光凸性（PS）效应，其中两个晶体在紫外线照射下都表现出爆裂、膨胀和分裂，通过纳米压痕研究明确地探测到了这一点。因此，这些发现可能为光致动智能材料的制造铺平道路。
