【 摘 要 】

In order to find out the microscopic environmental information on the nonionic reverse micelle of Triton X-100/n-hexanol/water in cyclohexane, an absorption and fluorescence spectroscopic study has been conducted using a methylene blue(MB). The information on the microscopic states of water in the polar core of the reverse micelle has been found by investigating complex formation and solvatochromic behavior between MB and Triton X-100. As a result, it was found that there exist three states in the polar core of the reverse micelle. The measured values of W(=[H2O]/[Surf]) for the three states of water are 0.71, 4.98, and 7.26, and the corresponding lifetimes of MB are 15.45 ns?.56, 12.27 ns?.79, and 8.28 ns?.82, respectively.
