Abstract

Aggregation-induced emission (AIE) systems face challenges in low-visibility environments, particularly for monitoring applications at night, due to optical and electrical signal feedback limitations. To address this issue, we developed fluorescent ionogels (TPPE-IL) by incorporating TPPE into an ionic liquid matrix. This innovative combination enhances the performance of wearable electronic devices through improved ionic conductivity, softness, and transparency. TPPE-IL exhibits significantly higher fluorescence intensity than hydrogel systems, making it more effective for nighttime monitoring. It demonstrates exceptional fluorescence stability during continuous stretch-release cycles (1000 s) and robust adhesive properties. Additionally, it exhibits excellent environmental stability and dehydration resistance. The sensitivity of TPPE-IL as a sensing material is 1.85, making it suitable for high-performance deformation sensors. Notably, the strain sensor based on TPPE-IL enables real-time monitoring of human and giant salamander movements at night, providing high sensitivity and reliable signal response. This study highlights the potential of TPPE ionogels in wearable electronics and ecological monitoring, offering a significant reference for developing new fluorescent ionogels.

基于四苯基荧光团的aie荧光离子凝胶

由于光学和电信号反馈的限制，聚集诱导发射（AIE）系统在低能见度环境中面临挑战，特别是在夜间监测应用中。为了解决这个问题，我们将TPPE掺入离子液体基质中，开发了荧光离子凝胶（TPPE- il）。这种创新的组合通过改善离子电导率、柔软度和透明度来增强可穿戴电子设备的性能。tpe - il表现出比水凝胶系统更高的荧光强度，使其更有效地用于夜间监测。它在连续拉伸释放周期（1000秒）和强大的粘接性能中表现出卓越的荧光稳定性。此外，它还具有优异的环境稳定性和抗脱水性能。tpe - il作为传感材料的灵敏度为1.85，适用于高性能变形传感器。值得注意的是，基于tpe - il的应变传感器可以实时监测人类和大鲵夜间的运动，提供高灵敏度和可靠的信号响应。本研究突出了TPPE离子凝胶在可穿戴电子和生态监测方面的潜力，为开发新型荧光离子凝胶提供了重要参考。
