The unique properties and processability of conducting and semiconducting organic materials have fascinated scientists since their discovery. Of this broad class of materials, conductive coordination polymers are of immense recent interest due to their innate modularity and tunability. However, these materials are typically generated as powders and, in some cases, single crystals which significantly limits possible processing and many applications. Herein, we report a method that enables solution-phase processing of a previously reported highly conductive coordination polymer, NiTTFtt (TTFtt = tetrathiafulvalenetetrathiolate), into thin films and conductive textiles. Thin films of NiTTFtt show record-breaking conductivity for a coordination polymer and unusual physical behavior that sheds light on the transport mechanisms in this glassy metallic material. Textiles coated with NiTTFtt are conductive and durable to air, water, washing, acid, base, and mechanical cycles. The properties and processability of NiTTFtt reported here make it notable among coordination polymers and conducting organic materials more broadly.
自从导电和半导体有机材料被发现以来，它们独特的性质和可加工性就一直吸引着科学家们。在这类广泛的材料中，导电配位聚合物因其固有的模块化和可调性而在最近引起了极大的关注。然而，这些材料通常以粉末形式生成，在某些情况下还会生成单晶，这极大地限制了可能的加工方式和许多应用。在此，我们报告了一种方法，该方法能够将先前报道的高导电配位聚合物NiTTFtt（TTFtt = 四硫富瓦烯四硫醇盐）进行溶液相加工，制成薄膜和导电纺织品。NiTTFtt薄膜展现出配位聚合物破纪录的电导率以及不同寻常的物理行为，这为这种玻璃态金属材料中的传输机制提供了线索。涂覆有NiTTFtt的纺织品具有导电性，并且对空气、水、洗涤、酸、碱和机械循环都具有耐久性。本文报道的NiTTFtt的性质和可加工性使其在配位聚合物以及更广泛的导电有机材料中脱颖而出。
