A series of long-chain imidazolium-based ionic liquids (ILs) 1-dodecyl-3-methylimidazolium chloride (1), 1,3-bis(octyloxycarbonylmethyl)imidazolium chloride (2) and 1-dodecyloxycarbonylmethyl-3-methyloxycarbonylmethylimidazolium chloride (3), were synthesized and evaluated as antimicrobials against a wide range of bacteria and fungi. Toxicological risks of selected compounds were assessed using the biomodels of various organizational and functional levels. All compounds demonstrated significant antibacterial and antifungal activity. The toxicity results indicate that ILs containing an ester functional group in the alkyl side chain exhibited much lower toxicity to D. magna and acetylcholinesterase inhibition than ILs with long alkyl chain without polar substituents, while toxicity toward Danio rerio was on a par. The HSA-binding properties of ILs have been investigated by FT-IR spectroscopy technique and the evidences have suggested that the test compounds could induce the protein unfolding and changes in the secondary structure of HSA. The docking studies were carried out to provide structural insights of the ILs–HSA-binding interactions. The docked compounds exhibit a high binding affinity to HSA and the hydrogen bonding, hydrophobic and electrostatic interactions played a major role in the process. ILs 2 and 3 may be perspective for further investigation as potential low-toxic biocides with high antimicrobial activity against reference and clinical multidrug-resistant strains.

Paragraph 0037; 0040-0042, (2021/11/03)
The invention provides a cyanine type modified compound with the structure of the formula (I), and also provides a preparation method of the cyanine type modified compound. The Vinamidinium-salt new synthetic route is developed, the process parameters are optimized, the yield of the intermediate is improved, the product quality is also good, and the effect of increasing the yield of the next step is crucial. In addition, since the cyanine-based modified compound contains more double bonds and strong electron-withdrawing groups, it can be used as an ultraviolet - blue light absorbent.
Preparation method of novel thermosensitive ionic liquid and method for synthesizing chloracetate catalytically
-
Paragraph 0027, (2019/04/02)
The invention discloses an acid functionalized-temperature controlled ternary heteropolyacid ionic liquid and a preparation method thereof, as well as an esterification method for synthesizing chloracetate catalytically. The structural formula of the heteropolyacid ionic liquid is as shown in a formula (I). The ionic liquid has a temperature responding characteristic during esterification reactionof chloroacetic acid and chloroacetic acid, is mixed with a reactant as one phase at the reaction temperature, and is further divided into two phases with the product when the temperature is reducedto a room temperature after the reaction. A catalyst and a reaction product can be separated quickly by simple filtration. The ionic liquid not only has the advantages of being convenient to recover and free of waste acid emission, but also has the characteristics of being high in esterification efficiency, good in repeated using performance and the like.
