Xwm:
Europium trifluoromethanesulfonate yog dawb crystalline khoom soluble nyob rau hauv polar organic solvents xws li ethanol, methanol thiab dimethylformamide.
Nws yuav decompose ntawm qhov kub thiab txias thiab tso tawm cov pa phem.
Nws yuav nqus dej noo thiab hnov mob nrog dej hauv huab cua.
Hauv cov organic chemistry, triflate, tseem paub los ntawm lub npe systematic trifluoromethanesulfonate, yog ib pab pawg ua haujlwm nrog cov mis CF₃SO₃−. Pawg triflate feem ntau yog sawv cev los ntawm −OTf, as opposed to −Tf (triflyl). Piv txwv li, n-butyl triflate tuaj yeem sau ua CH₃CH₂CH₂CH₂OTf.

Daim ntawv thov
Europium trifluoromethanesulfonate tuaj yeem siv los ua fluorescence qhov chaw rau lub teeb gels thiab fluorescent probes. Nws muaj peev xwm emit liab fluorescence, yog li nws muaj ntau yam kev siv nyob rau hauv bio fluorescence imaging, biosensing thiab optoelectronic li.
Nws kuj tseem siv tau los ua ib qho catalyst hauv organic synthesis.
Nws yog ib qho dej-tiv taus Lewis acid siv hauv Aldol cov tshuaj tiv thaiv ntawm silyl enol ethers nrog aldehydes.
