Electronic microdevices of self-bending coronene crystals are developed to reveal an unexplored link between mechanical deformation and crystal function. First, a facile approach towards length/width/curvature-controllable micro-crystals through bottom-up solution crystallization was proposed for high processability and stability. The bending crystal devices show a significant increase beyond seven orders of magnitude in conductivity than the straight ones, providing the first example of deformation-induced function enhancement in crystal materials. Besides, double effects caused by bending, including the change of π electron level as well as the enhancement of carrier mobility, were determined, respectively by the X-ray photoelectric spectroscopy and X-ray crystallography to coexist, contributing to the conductivity improvement. Our findings will promote future creation of flexible organic crystal systems with deformation-enhanced functional features towards customized smart devices.

更好地弯曲：用于定制电子设备的具有可控曲率和与曲率相关的电导率的柔性有机单晶

自弯曲冠烯晶体的电子微器件被开发出来，以揭示机械变形和晶体功能之间尚未探索的联系。首先，提出了一种通过自下而上的溶液结晶制备长度/宽度/曲率可控微晶的简便方法，以实现高加工性和稳定性。弯曲晶体器件的电导率比直器件显着增加了七个数量级，这是晶体材料变形诱导功能增强的第一个例子。此外，弯曲引起的双重效应，包括 π 电子能级的变化以及载流子迁移率的增强，分别通过 X 射线光电光谱和 X 射线晶体学确定共存，有助于提高电导率。
