UV responsive liposomes were prepared with egg phosphatidylcholine (egg PC) and 7-acetoxycoumarin. 7-acetoxycoumairn (7-ATC) show an photo reactivity under UV irradiation. Under the light wavelength at 365nm, 7-ATC formed dimer and under the light of wavelength at 254nm, 7-ATC cleaved to monomer again. Dimerization was investigated from liposome with 7-ATC and without 7-ATC. The optimum ratio of 7-ATC to egg PC was 1:8. 5(6)-carboxy fluorescence (CF) was released from liposome under 254nm UV irradiation. Due to the fluorescence dye was not stable under 365nm UV irradiation. 7-ATC dimer was prepared under 365nm UV irridation first, used to prepared. Release of CF containing in liposome with 7-ATC dimer was higher than that in liposome without 7-ATC dimer. 7-ATC dimer was located in liposome bilayer membrane because it was hydrophobic. When irradiate at 254nm UV light, 7-ATC dimer become monomer and liposome bilayer membrane was very unstable. As a result, liposomes were disintegrated so that CF was released.
