摘要:
A novel crown ether-azobenzene derivative (CAD) was synthesized. It was formed in a stable monolayer at air-water interface, and could be transferred to both ITO glasses and CaF2 substrates with near unity of transfer ratio. Under irradiations of UV and visible light,the CAD molecules showed a highly efficient photochromic behavior in the rigid Langmuir-Blodgett films.The trans-cis conversion rate reached 76%,comparable with that obtained in chloroform solution.
