| Research Abstract |
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.
