Humidity is one of the most important indicators affecting human health. Here, a pair of covalent organic frameworks (COFs) of positional isomers (p-COF and o-COF) for indoor humidity regulation is reported. Although p-COF and o-COF have the same sql topology and pore size, they exhibit different water adsorption behaviors due to the subtle differences in water adsorption sites. Particularly, o-COF exhibits a steep adsorption isotherm in the range of 45-65% RH with a hysteresis loop, which is perfectly suitable for indoor humidity regulation. In the laboratory experiment, when the humidity of the external environment is 20-75% RH, o-COF can control the humidity of the room in the range of 45-60% RH. o-COF has shown great potential as a dual humidification/dehumidification adsorbent for indoor humidity regulation.
湿度是影响人类健康的最重要指标之一。在此，报道了一对用于室内湿度调节的位置异构体共价有机框架（COF）（对COF和邻COF）。尽管对COF和邻COF具有相同的sql拓扑结构和孔径，但由于水吸附位点的细微差异，它们表现出不同的水吸附行为。特别是，邻COF在45-65%相对湿度范围内呈现出具有滞后环的陡峭吸附等温线，这非常适合室内湿度调节。在实验室实验中，当外部环境湿度为20-75%相对湿度时，邻COF可将房间湿度控制在45-60%相对湿度范围内。邻COF作为用于室内湿度调节的双加湿/除湿吸附剂已显示出巨大潜力。
