Multi-functional fluorinated ionic liquid infused slippery surfaces with dual-responsive wettability switching and self-repairing

Stimuli responsive slippery surfaces with controllable wettability have attracted much attention due to their potential application in many fields. However, most of these surfaces only adopted paraffin as the lubricant oil and achieved wettability transformation just by heating. In addition, the self-repairing properties of smart slippery surfaces have rarely been reported. Hence, challenges still remain in fabricating multiple responsive slippery surfaces based on other lubricants possessing self-repairing properties. Here, a smart slippery surface with controllable wettability was fabricated by using solid/liquid fluorinated ionic liquids (FILs) as lubricants and fluoropolymer films as the underlying substrates. The FIL, a thermo-responsive phase-transition material, was synthesized by ionic exchange and the substrate exhibited good self-repairing properties and magnetic-thermal and photo-thermal responses. By tuning the substrate temperature under light irradiation or magnetic field to change the phase state of the FIL, the surface could realize wettability conversion. Besides, the responsive temperature can be adjusted by tuning the melting temperature (Tm) of the FIL. The FIL was first synthesized and there was no report employing FILs as the lubricants to realize the wettability change of slippery surfaces. This work provided a new type of lubricant to prepare intelligent slippery surfaces, thus advancing the application of slippery surfaces in liquid transport devices.

The reaction of per(poly)fluoroalkanesulfonyl azides with tertiary and secondary amines: Generation and trapping of enamines

Per(poly)fluoroalkanesulfonyl azides decomposed readily at 0°C or ambient temperature in the presence of tertiary or secondary amines via a single electron transfer process and gave the corresponding fluoroalkanesulfonyl amides and N-fluoroalkanesulfonyl amidines. The formation of amidines was reasonably explained in terms of trapping of N-substituted vinylamine generated in situ with the azides.

Synthesis and investigation of inhibition effect of fluorinated sulfonamide derivatives on carbonic anhydrase

Series of perfluoroalkanesulfonamides 1, sodium salt of perfluoroalkanesulfonamides 2 and polyfluoroalkanesulfonamides 3 derivatives were synthesized and characterized by 1H NMR, 13C NMR, 19F NMR, IR and HRMS. Inhibition effects of these compounds on bovine carbonic anhydrase (bCA) and human carbonic anhydrase isoenzyme II (hCA) have been investigated. Comparing IC50 values of the synthesized molecules 1, 2 and 3, it has been found that compound 2b is a more potent inhibitor than acetazolamide on hCA. Moreover 2b does not present cellular toxicity on sheep red globules.

Photochemical C?H Amination of Ethers and Geminal Difunctionalization Reactions in One Pot

A mild, atom-economic, and metal-free α-C?H amination of ethers using relatively stable nonafluorobutanesulfonyl (nonaflyl, Nf) azide as the aminating reagent to give N-sulfonyl hemiaminals is reported. This enables unprecedented C(sp3) difunctionalization reactions, leading to diverse functionalized amino group containing compounds starting from simple ethers in one pot.
