Film-based fluorescent sensors have become an important field of sensor research due to abundant acquirable signals, real-time monitoring, and ease of miniaturization and integration, where chemically sensitive films are the most vital component of the sensor devices. In this feature article, we introduce hardware structures of film-based fluorescent sensors following the examination/investigation of the recent progress of such sensors with perylene bisimide (PBI) derivatives as sensing fluorophores in the films. PBI derivatives were specially chosen because of their outstanding chemical, photochemical, and thermal stabilities as well as their unusual high-fluorescence quantum yields. And finally, we provide a prediction for the future developments and challenges of this emerging field.
基于薄膜的荧光传感器由于具有丰富的可获取信号、实时监测以及易于小型化和集成等特点，已成为传感器研究的一个重要领域，其中化学敏感薄膜是传感器装置中最为关键的组件。在这篇专题文章中，我们在考察/研究了以苝二酰亚胺（PBI）衍生物作为薄膜中传感荧光团的此类传感器的最新进展之后，介绍了基于薄膜的荧光传感器的硬件结构。选择PBI衍生物是因其具有出色的化学稳定性、光化学稳定性和热稳定性，以及非同寻常的高荧光量子产率。最后，我们对这一新兴领域的未来发展和挑战进行了预测。
