Real-time optical and electronic sensing with a β-amino enone linked, triazine-containing 2D covalent organic framework

[This repository contains the raw and source data for the manuscript "<strong>Real-time optical and electronic sensing with a β-amino enone linked, triazine-containing 2D covalent organic framework</strong>".] Fully-aromatic, two-dimensional covalent organic frameworks (2D COFs) are hailed as candidates for electronic and optical devices, yet to-date few applications emerged that make genuine use of their rational, predictive design principles and permanent pore structure. Here, we present a 2D COF made up of chemoresistant β-amino enone bridges and Lewis-basic triazine moieties that exhibits a dramatic real-time response in the visible spectrum and an increase in bulk conductivity by two orders of magnitude to a chemical trigger - corrosive HCl vapours. The optical and electronic response is fully reversible using a chemical switch (NH₃ vapours) or physical triggers (temperature or vacuum). These findings demonstrate a useful application of fully-aromatic 2D COFs as real-time responsive chemosensors and switches.本仓库包含论文《基于β-氨基烯酮（β-amino enone）连接、含三嗪（triazine）结构的二维共价有机框架（2D covalent organic framework, 2D COF）的实时光电传感》的原始与源数据。 全芳香族二维共价有机框架（2D COFs）被广泛视为光电器件的候选材料，但迄今为止，真正利用其可理性预测的设计原则与永久孔道结构的应用仍寥寥无几。本研究报道了一种由耐化学腐蚀的β-氨基烯酮桥连结构与路易斯碱性（Lewis-basic）三嗪官能团构成的2D COF，其在可见光谱范围内展现出显著的实时响应；当遭遇腐蚀性氯化氢（HCl）蒸气这一化学触发剂时，其体相电导率提升两个数量级。该材料的光电响应可通过化学切换手段（氨气（NH₃）蒸气）或物理刺激手段（温度调控或真空环境）实现完全可逆。上述研究成果证实，全芳香族2D COFs可作为实时响应型化学传感器与开关器件，具备切实的应用价值。
