摘要研究了基于双（乙二氧基）四硫富瓦烯（BEDO-TTF）配合物的金属网状物掺杂聚合物复合材料的输运和光学性质，并与相应块体晶体的结构和物理性质进行了比较。将含有分子分散供体的聚碳酸酯（PC）膜表面暴露于溶剂/（碘或溴）蒸气中，供体转化为电荷转移（CT）复合物，其主导复合物的导电和热电性能。两个膜表面掺杂溴和碘是良好的导电性，显示金属行为下降到低温。部分氧化的BEDO-TTF分子的高导电态的特征CT带出现在红外区域。然而，与相应的块状晶体相比，对于垂直于膜表面的入射光，施主分子的分子内激发的抑制大大减小。BEDO-TTF的PC膜...
Abstract Transport and optical properties of the metallic reticulate-doped polymer composites based on bis(ethylenedioxy)tetrathiafulvalene (BEDO-TTF) complexes are investigated, and compared with the structural and physical properties of the respective bulk crystals. Exposing the surface of polycarbonate (PC) film containing the molecularly dispersed donor to the solvent/(iodine or bromine) vapor converted the donor into charge-transfer (CT) complexes, which dominate the conducting and thermoelectric properties of the composites. Both film surfaces doped with bromine and iodine are well conducting, showing metallic behavior down to low temperatures. A characteristic CT band for the highly conducting states of the partially oxidized BEDO-TTF molecules appeared in the infrared region. However, compared with the respective bulk crystal, absorptions of the intramolecular excitation of the donor molecules are greatly diminished for the incident light perpendicular to the film surface. The PC film of (BEDO-TTF...
