摘要

开发具有柔性、压电变色性和光波导等综合特性的有机单晶体,对于推动新型光电器件的发展至关重要。本文制备了一种基于吩噻嗪的长针状有机塑料晶体,并在紫外光激发下发出明亮的黄绿色荧光。通过金刚石砧电池对其压电变色特性的研究发现,这种基于吩噻嗪的材料在相对较低的压力(0-0.6 GPa)下具有压力诱导的发射增强效应。此外,还对该晶体在线性和塑性变形状态下进行了光波导测试,结果显示其透光性能没有明显衰减。这种基于吩噻嗪的晶体具有柔韧性、压电变色性和光波导特性,可用作开发集成压力传感器的传感材料。

Phenothiazine-Based Organic Single Crystal with Flexibility, Piezochromism, and Fluorescent Waveguide Properties

Phenothiazine-Based Organic Single Crystal with Flexibility, Piezochromism, and Fluorescent Waveguide Properties

The development of organic single crystals with combined properties, including flexibility, piezochromism, and optical waveguiding, holds paramount importance for advancing new optoelectronic devices. Herein, a long, needle-shaped organic plastic crystal based on phenothiazine was fabricated, and it emits bright yellow-green fluorescence under ultraviolet light excitation. Investigations into its piezochromism property via a diamond anvil cell revealed that this phenothiazine-based material performed a pressure-induced emission enhancement effect under relatively low pressures (0–0.6 GPa). Furthermore, optical waveguide tests were conducted on the crystal in both linear and plastic deformation states, and the results revealed no significant attenuation of its light transmission properties. This phenothiazine-based crystal exhibits flexibility, piezochromism, and optical waveguiding properties, which will be valuable as a sensing material for developing integrated pressure sensors.
