Poor solubility of π-conjugated two-dimensional polymers (C2Ps) has been a significant roadblock in incorporating these emergent materials into electronic devices by simple solution processing. Here, we report a rational design of triphenylene-based building blocks that condense via a series of reversible reactions for self-error-correction and a final irreversible fixation to form a pyrazine motif, which leads to the formation of crystalline C2Ps in solution without any aid of template or preorganization. Unlike typical covalent organic frameworks, remarkably, these materials remain dispersed as single- to few-layer films in solution, presumably because of protonation of pyrazine motifs by the strong acid employed in the synthesis. The C2Ps can be easily drop-cast onto solid surfaces for characterization and fabrication of electronic devices. The thin polymer films display a long-range internal order and exhibit high hole mobility up to 4 cm²V⁻¹s⁻¹, the highest among C2Ps, which paves the way to design high-performance optoelectronic devices.

π共轭二维聚合物（C2P）的不良溶解性已成为通过简单的溶液处理将这些新兴材料掺入电子设备的重要障碍。在这里，我们报告了基于三苯撑的结构单元的合理设计，该结构单元通过一系列可逆的反应进行冷凝，以进行自我错误校正和最终不可逆的固定，从而形成吡嗪基序，从而导致溶液中无任何形成的结晶C2P模板或预组织的帮助。与典型的共价有机骨架不同，这些材料显着地以单层至几层薄膜的形式分散在溶液中，这可能是由于合成中所用的强酸使吡嗪基序质子化。可将C2P轻松滴铸到固体表面上，以表征和制造电子设备。² V ^-1 s ^-1，是C2P中最高的，这为设计高性能光电器件铺平了道路。
