The Microcrystals of BEDT-TTF and BEDO-TTF Polyiodides Forming the Conducting Networks within Polymer Film surface and Their Transformations

New results on morphology and structure of microcrystals of bis-(ethylenedithio)tetrathiafulvalene (BEDT-TTF or ET) and bis(ethylenedioxy)tetrathiafulvalene (BEDO-TTF or BO) polyiodide salts formed within surface layers of polymer films by a two step reticulate doping technique and their transformations are discussed. The architecture of the microcrystalline conducting network was studied by STM and AFM. X-ray diffraction studies of microcrystals of ET salts in polymer matrix and structure-properties relationships are discussed. The thermal transformation of microcrystals of _-ET2I3 in polymer matrix to _-ET2I3 was followed in situ by X-ray diffraction and a new example of the transformation of microcrystals of BO salt in polymer matrix by annealing is shown.
