Intelligent Polymers for Opto-Electronic Applications

Thin films of poly(benzothiazole) containing thiophene in main chains were success fully prepared at air/water interface by using Langmuir-Blodgett (LB) method and they were transferred onto quartz plate as multi-layers built-up films. Third harmonic generation of the thin film was measured as χ ³ = 10 ^-11 esu which was 10 times higher than that of normal poly(ben zothiazole) without having thiophene. New ion conductive polymer complexes were formed by dissolving poly(1-butyl-4-vinylpyri dinium) salts into room temperature molten salts consisting of 1-butylpyridinium salts and aluminium chloride. The viscoelastic films were fabricated from the molten salts added at least 10 mol % of the polypyridinium salts. The ionic conductivities of the polymer complexes were in the range of 10 ^-3 -10 ^-4 Scm ^-1 at room temperature and were affected by their composition.
