英文摘要: A novel charge-transfer complex film: copper-(n-propyl ester 7,7,8,8- tetracyanoquinodimethane-2,5-ylene-(3-propionic acid)) (Cu-TCNQ(C2H4COOC3H7)(2)) Was prepared by spin-coating. Absorption spectra, green-light (514.5nm) static rewritable optical recording properties and rewritable mechanism of this film were studied. The results show that there are two strong absorption peaks at 388nm and 675nm, which can be assigned to electronic transitions in anion radical TCNQ(C2H4COOC3H7)(2)(-). Green-light optical storage experimental results of this film were as follows: write-in power was 9 in W, pulse duration was 80 ns; erasing power was 4 m W, pulse duration was 500 ns, the reflectivity contrast C greater than or equal to 15 %; number of write-erase cycles N greater than or equal to 100. It is found that the realization of rewritable optical storage of the Cu-TCNQ(C2H4COOC3H7)(2) film is related to the reversible changes of the optical properties, which is caused by the reversible charge transfer between copper and n-propyl ester 7,7,8,8- tetracyanoquinodimethane-2,5-ylene-(3-propionic acid) in the complex through inducement of laser irradiation.
