Luminescent organic thin films are widely used in optoelectronic devices for sensing, imaging and data processing. Herein, the transition to a flexible form is accompanied by a number of challenges associated with a limited endurance and bending-dependent properties. Here we report a study on the growth of thin films based on thiophene-based luminescent molecular crystals (MC) on a flexible polypropylene (PP) substrate of a various thicknesses (400 m to 50 m). The resulting flexible thin films demonstrate the stability of their luminescent properties under mechanical bending (up to 100 times) at ambient conditions, which pave the way for large scale production of planar optoelectronic components.

柔性基板上噻吩基发光薄膜的自组装。

发光有机薄膜广泛应用于传感、成像和数据处理的光电器件中。在此，向柔性形式的转变伴随着与有限的耐久性和弯曲相关特性相关的许多挑战。在这里，我们报告了一项关于在不同厚度（400 m 至 50 m）的柔性聚丙烯 (PP) 基板上生长基于噻吩基发光分子晶体 (MC) 的薄膜的研究。所得柔性薄膜在环境条件下机械弯曲（高达100次）下表现出发光性能的稳定性，这为大规模生产平面光电元件铺平了道路。
