In 2019,ACS Applied Nano Materials included an article by Cui, Wei-Rong; Zhang, Cheng-Rong; Jiang, Wei; Liang, Ru-Ping; Qiu, Jian-Ding. HPLC of Formula: 34374-88-4. The article was titled 《Covalent Organic Framework Nanosheets for Fluorescence Sensing via Metal Coordination》. The information in the text is summarized as follows:
Covalent organic framework nanosheets (COF NSs) provide well-ordered π-π structures that can be used to develop luminescent materials. However, most COF NSs have problems of weak luminescence and low fluorescence quantum yield. In this work, the authors prepared covalent organic framework nanosheets (Bpy-NSs) with good water dispersibility, nitrogen-rich functional groups, and regular pore structure. The authors explored the coordination of Bpy-NSs with Al3+ to eliminate the fluorescence quenching process caused by photoinduced electron transfer (PET). Thus, the fluorescence “”turn-on”” signal linearly increases with Al3+ concentration, achieving a 15.7-fold improved in fluorescence, and the absolute fluorescence quantum yield increased from 0.15 to 1.74%. Furthermore, this is the first COF fluorescence sensor that can be used for high sensitivity and selectivity detection of Al3+ in the aqueous phase. The authors anticipate that the expansion of metal ions coordination strategy in the aqueous phase will not only significantly enhance the fluorescence of COF NSs but also extend the functional range of COF NSs. The experimental process involved the reaction of 2,4,6-Trihydroxybenzene-1,3,5-tricarbaldehyde(cas: 34374-88-4HPLC of Formula: 34374-88-4)
