Analysis of Film Characteristics of Long Alkyl Chain-Contained 6-Nitro Spiropyran Fabricated by LB and Spin-Coating Method

초록

The photochromic properties of the films consisted of 6-nitro spiropyran with long alkyl chain were investigated as the fabrication method of films. The long alkyl chain-contained 6-nitro spiropyran films fabricated by spin coating method and by Langmuir-Blodgett technique also showed its native optical property. The photochromism of Langrnuir-Blodgett films and spin coating films of 6-nitro spiropyran with long alkyl chain were investigated with various fabrication conditions of Langmuir-Blodgett films and spin coating method. The J-aggregate of 6-nitro spiropyran in the Langmuir-Blodgett films and in the spin coating films were occurred. The j-aggregate of 6-nitro spiropyran film by the spin-coating method was disappeared by the long irradiation of UV light.
