Abstract
A Malachite Green derivative carrying a long alkyl chain affords photogenerated amphiphilicity by UV irradiation. The behavior of the photoresponsive Malachite Green surfactant was studied in mixed micelle solutions containing cetyltrimethylammonium chloride. We found that the Malachite Green surfactant increases the solubility of oily substance by UV irradiation. The role of the Malachite Green surfactant has been investigated by dynamic light scattering and spectroscopic analysis. The Malachite Green surfactant causes an increase in the micelle size, and its hydrophilic head group lies at the micellar interface. The mechanism of the photoinduced uptake of oily substances is discussed at the viewpoint of the microscopic location of the Malachite Green surfactant in the micelle.
