  Ionic liquid-derived charged polymers to show highly thermoresponsive LCST-type transition with water at desired temperatures

  摘要：

  具有适当疏水性的聚合离子液体（poly(IL)）会与纯水和盐水溶液发生强烈的温度敏感型 LCST 相变，由此产生的水合聚合离子液体（poly(IL)）还会在环境温度下发生急剧且可逆的液态到凝胶的转变。

  The temperature-induced phase transition behaviors of a thermoresponsive ionic liquid (tributylhexylphosphonium 3-sulfopropylmethacrylate, [P4,4,4,6][MC3S]) and its polymer (poly-tributylhexylphosphonium 3-sulfopropylmethacrylate, P[P4,4,4,6][MC3S]) have been investigated using DSC, optical microscopy, temperature-variable 1H NMR, and FT-IR in combination with two-dimensional analysis methods, including perturbation correlation moving window (PCMW) and two-dimensional correlation spectroscopy (2Dcos). We found that there exists a distribution gradient of water molecules in P[P4,4,4,6][MC3S] ranging from hydrophobic backbones to hydrophilic sulfonates. Linked together by covalent bonds, P[P4,4,4,6][MC3S] would form an “urchin-like” structure, which can improve its stability and strengthen the gradient distribution of water. Finally, 2Dcos was employed to elucidate the sequential order of chemical group motions during heating. It is concluded that both [P4,4,4,6][MC3S] and P[P4,4,4,6][MC3S] experience the anionic dominated phase transition process. Moreover, the driving force for the phase transitions is shown to be the dehydration of hydrophobic ester carbonyls.

  采用 DSC、光学显微镜、变温 1H NMR 和 FTIR 等二维分析方法，包括扰动偏振分析法，研究了热致伸缩性离子液体（3-磺丙基甲基丙烯酸三丁基己基膦，[P4,4,4,6][MC3S]）及其聚合物（3-磺丙基甲基丙烯酸聚三丁基己基膦，P[P4,4,4,6][MC3S]）的温度诱导相变行为、6][MC3S]）的研究采用了 DSC、光学显微镜、变温 1H NMR 和 FT-IR 以及二维分析方法，包括扰动相关移动窗 (PCMW) 和二维相关光谱 (2Dcos)。我们发现 P[P4,4,4,6][MC3S]中存在着从疏水性骨架到亲水性磺酸盐的水分子分布梯度。通过共价键连接在一起，P[P4,4,4,6][MC3S]将形成 "海胆状 "结构，从而提高其稳定性并加强水的梯度分布。最后，利用 2Dcos 阐明了加热过程中化学基团运动的先后顺序。结论是[P4,4,4,6][MC3S]和 P[P4,4,4,6][MC3S] 都经历了阴离子主导的相变过程。此外，相变的驱动力被证明是疏水酯羰基的脱水作用。

The LCSTs of 31, 26, 22, and 18 °C were obtained from 2.5, 5.0, 7.5, and 10.0 wt% aqueous solutions of [P4446][C3S].
