The design of molecular compounds that exhibit flexibility is an emerging area of research. Although a fair amount of success has been achieved in the design of plastic or elastic crystals, realizing multidimensional plastic and elastic bending remains challenging. We report herein a naphthalidenimine–boron complex that showed size‐dependent dual mechanical bending behavior whereas its parent Schiff base was brittle. Detailed crystallographic and spectroscopic analysis revealed the importance of boron in imparting the interesting mechanical properties. Furthermore, the luminescence of the molecule was turned‐on subsequent to boron complexation, thereby allowing it to be explored for multimode optical waveguide applications. Our in‐depth study of the size‐dependent plastic and elastic bending of the crystals thus provides important insights in molecular engineering and could act as a platform for the development of future smart flexible materials for optoelectronic applications.

萘二甲酰亚胺-硼配合物的塑料/弹性有机晶体表现出灵活的光波导特性。

具有灵活性的分子化合物的设计是一个新兴的研究领域。尽管在塑料或弹性晶体的设计上已经取得了相当大的成功，但是实现多维的塑料和弹性弯曲仍然具有挑战性。我们在此报告了一种萘二甲胺-硼配合物，该配合物表现出尺寸依赖性的双重机械弯曲行为，而其母体席夫碱则较脆。详细的晶体学和光谱分析揭示了硼在赋予有趣的机械性能方面的重要性。此外，在硼络合之后，该分子的发光被打开，从而使其可以用于多模光波导应用。
