Study on H-bonded structures in aqueous solution using laser-induced matrix isolation method

利用拉曼光谱研究了具有较低临界溶解温度的2-丁氧基乙醇（2BE）和水的二元液体混合物。拉曼光谱的浓度依赖性表明，当2BE的摩尔分数为0.01-0.1时，即使在室温下也形成胶束状微相。研究了螺吡喃作为光响应性溶质在水和2BE体系中的光诱导相分离和相混合。结果表明，汞（MC）型溶液的相分离温度高于螺吡喃（SP）型溶液。

The binary liquid mixture of 2-butoxyethanol (2BE) and water, which has its lower critical soluble temperature, has been studied using Raman spectroscopy. The concentration dependence of Raman spectra implies that micelle-like micro-phases forms even at room temperature when the mole fraction of 2BE is 0.01-0.1. Photo-induced phase separation and phase mixing of water and 2BE, in which spiropyran was dissolved as a photo-responsive solute, was investigated. It was found that the phase separation temperature of the merocyanine (MC) form solution was higher than that of the spiropyran (SP) form solution.
