Abstract
Conducting reticulate doped polymeric films containing BEDT-TTF iodide crystalline network were annealed in order to transform the crystalli tes into crystal phases with metallic conductivity. Measured optical a bsorption spectra show that annealing shifts the absorption band to hi gher frequencies and increases the transparency of the films. This beh avior corresponds to the transformation of the alpha-phase into the su perconducting alpha(t)-phase observed in (BEDT-TTF)(2)I-3 single cryst als.
