Abstract
New conducting bilayer films (BL-film) containing (BEDT-TTF)(2)(I3Br1-x)(3) molecular metals as active components have been prepared. The effect of va rious parameters of the BL-film preparation on the conducting layer composi tion was systematically studied by X-ray, Raman, EPR, and SEM. It was shown that the conducting layer of new BL-films is formed by "c " oriented (BEDT -TTF)(2)(IxBr1-x)(3) nanocrystals which contain a set of the IBr2-, I2Br-, and/or I-3(-) anions. It was found that the alpha' --> beta phase transitio n takes place in the (BEDT-TTF)(2)(IxBr1-x)(3) nanocrystals under film anne aling. Some of the new composite BL-films, being flexible and transparent, reveal a metal-like temperature dependence of resistance down to nitrogen t emperature.
