The performance of a film-based fluorescent sensor is highly dependent on the innovative design of the sensing films aiming to elevate usability of sensing units, and enhance mass transfer of analytes within the fluorescent adlayer. Herein, a highly porous and uniform fluorescent nanofilm which is fabricated through an interfacially confined dynamic-covalent reaction between benzene-1,3,5-tricarbo-hydrazide and a mono-boron complex of 8-hydroxy-quinoline is reported. Remarkably, the thicknesses of the nanofilms prepared in this way can be modulated from tens to hundreds of nanometers. In addition, the nanofilms demonstrate much improved photochemical stability. Sensing performance studies reveal that the nanofilm is super-sensitive and selective to the presence of amines, especially methylamine (MA) in vapor phase. Specifically, the detection limit to MA is lower than 2.82 mg m−3, and the presence of the vapors of water, aromatic hydrocarbons, aliphatic hydrocarbons, alcohols, ketones, and other common organic compounds showed little effect upon the sensing. Moreover, the sensing is highly reversible. With the innovation in adlayer structure, substrate effect as commonly found in routine film-based sensing is avoided, which must bring convenience for device making. In this work, different film-based sensors are fabricated, suggesting their potential applications in various scenarios.

具有增强的气相甲胺传感性能的单硼配合物基荧光纳米薄膜
基于薄膜的荧光传感器的性能高度依赖于传感薄膜的创新设计,旨在提高传感单元的可用性,并增强荧光层内分析物的传质。本文报道了一种高度多孔且均匀的荧光纳米薄膜,该薄膜是通过苯-1,3,5-三碳酰肼和 8-羟基喹啉的单硼配合物之间的界面限制动态共价反应制备的。值得注意的是,以这种方式制备的纳米薄膜的厚度可以在几十到几百纳米之间进行调节。此外,纳米薄膜表现出大大改善的光化学稳定性。传感性能研究表明,纳米薄膜对胺的存在具有超灵敏和选择性,尤其是气相中的甲胺 (MA)。具体来说,-3,水蒸气、芳香烃、脂肪烃、醇、酮和其他常见有机化合物的存在对传感几乎没有影响。此外,传感是高度可逆的。随着adlayer结构的创新,避免了常规薄膜传感中常见的基板效应,这必须为器件制造带来便利。在这项工作中,制造了不同的基于薄膜的传感器,表明它们在各种场景中的潜在应用。
