COFs (including keto-enamine, azine and hydrazone linked COFs) and imine-linked 3D COFs by using deep eutectic solvents (DESs) as green media under ambient conditions. The COFs are highly crystalline and show good surface areas, and were obtained within 2 h at room temperature in an open reaction system. More importantly, we also extended this protocol to the synthesis of a new azo-based 3D COF with

The efficient removal and storage of radioactive nuclear contaminants of iodine has been realized by deep eutectic solvents (DESs) due to the formation of halogen bonding (XB).
通过形成卤素键(XB),深共熔溶剂(DESs)实现了对碘放射性核污染物的高效去除和储存。
Norharmane prototropism in choline chloride-based deep eutectic solvents
3-phenylpropionic acid, and malonic acid, respectively, only cationic form is supported. As the cationic form is preferred more over the neutral form of norharmane in the excited-state, DESs with HBDs tetraethylene glycol, 3-phenylpropionic acid, and malonic acid, respectively, support only cationic form in the excited-state. DES with glycerol also supports only the cationic form in the excited-state, DES with
It has surprisingly been discovered that it is possible to stabilise biomolecules such as RNA, DNA and proteins in biological samples such as cells, tissues, biopsies and blood using deep eutectic solvents (DES). It has also been discovered that DES mixtures can be used to fix and preserve cell morphology in biological samples such as tissue blocks, cancer biopsies and whole blood. This invention describes methods to stabilise and preserve biomolecules, whole cells, tissues, blood and biological samples using DES mixtures.
Natural deep eutectic solvent extraction of chlorogenic acid from <i>Eucommia</i> leaves: high extractability, stability, antibacterial, and antioxidant activity
Chlorogenic acid (CGA) is a natural compound with potent antioxidant and antibacterial properties that can be extracted from Eucommia leaves (EL). In this study, we investigated eight naturaldeepeutecticsolvents (NADES) for their effectiveness in extracting CGA from EL. The extractability, stability, antibacterial and antioxidantactivity of the CGA extracted by NADES were evaluated and compared
