The development of modern optoelectronic devices increases the need for lightweight and flexible transparent conductors. It is thus essential to develop new eco-friendly materials that can be easily processed for the fabrication of such devices. For this purpose, the synthesis of self-doped, highly conducting, transmissive, and water-processable polythiophene derivatives was performed via the direct heteroarylation polymerization method and a protection/deprotection strategy. Stable conductivities up to 1000 S cm have been obtained. Champion materials ( and ) were scaled and processed via the roll-to-roll compatible slot-die coating method to demonstrate their large area applicability. The best coated films exhibited optical transmittance greater than 79% at 550 nm with sheet resistances of 116 Ω □. These values are comparable to indium-tin oxide on plastic and thus present a viable alternative to metal oxide-based electrodes.
现代光电器件的发展增加了对轻质且柔性透明导体的需求。因此，开发能够易于加工以制造此类器件的新型环保材料至关重要。为此，通过直接杂芳基化聚合法和保护/脱保护策略进行了自掺杂、高导电、透射且可水加工的聚噻吩衍生物的合成。已获得高达1000 S/cm的稳定电导率。通过卷对卷兼容的狭缝模涂覆方法对优异材料（和）进行了规模化制备和加工，以证明其大面积适用性。最佳涂覆薄膜在550 nm处表现出大于79%的光学透过率，方阻为116 Ω/□。这些值与塑料上的氧化铟锡相当，因此是基于金属氧化物的电极的可行替代方案。
