11-苄硒基十一羧酸铵盐的双重刺激响应性质
Dual stimuli-responsive properties of ammonium 11-benzylselanyl undecanoate
摘要
Abstract
A kind of redox and CO2/N2 dual stimuli-responsive surfactant ammonium 11-benzylselanyl undecanoate (BSeUA) was synthesized.The molecular structure change of BSeUA triggered by redox and CO2/N2 was studied with Fourier Transform Infrared Spectroscopy (FT-IR),Nuclear Magnetic Resonance (NMR) and Electrospray Ionization Mass Spectrometry (ESI-MS).Results show that the selenium-containing group can be reversibly switched between bivalent selenide (-Se-) and tetravalent selenoxide (-Se =O) by alternately adding hydrogen peroxide and hydrazine hydrate,and the CO2-sensitive group can be reversibly switched between carboxylate (-COO-) and carboxylic acid (-COOH) by bubbling CO2 and N2.Thus,the BSeUA-stabilized emulsion can be switched reversibly between de-emulsification and re-emulsification over five times at least.No obvious adverse changes in droplet size and the relative stability of the regenerated emulsions are observed.关键词
