摘要：

Optical and photochromic properties of spiropyran-doped DNA-surfactant complex films have been studied. They strongly depended on the type of spiropyran as well as the type of surfactant. Spiropyrans containing the oxazine ring and intercalated into DNA showed very rapid photochromic response. It is also shown that photochromic response times are expected much faster by increasing the intensity of the excitation light.
