Porous polymers have been recently recognized as one of the most important precursors for fabrication of heteroatom-doped porous carbons due to the intrinsic porous structure, easy available heteroatom-containing monomers and versatile polymerization methods. However, the heteroatom elements in as-produced porous carbons are quite relied on monomers. So far, the manipulating of heteroatom in porous polymer derived porous carbons are still very rare and challenge. In this work, a sulfur-enriched porous polymer, which was prepared from a diacetylene-linked porous polymer, was used as precursor to prepare S-doped and/or N-doped porous carbons under nitrogen and/or ammonia atmospheres. Remarkably, S content can sharply decrease from 36.3% to 0.05% after ammonia treatment. The N content and specific surface area of as-fabricated porous carbons can reach up to 1.32% and 1508 m2·g−1, respectively. As the electrode materials for electrical double-layer capacitors, as-fabricated porous carbons exhibit high specific capacitance of up to 431.6 F·g−1 at 5 mV·s−1 and excellent cycling stability of 99.74% capacitance retention after 3000 cycles at 100 mV·s−1. Furthermore, as the electrochemical catalysts for oxygen reduction reaction, as-fabricated porous carbons presented ultralow half-wave-potential of 0.78 V versus RHE. This work not only offers a new strategy for manipulating S and N doping features for the porous carbons derived from S-containing porous polymers, but also paves the way for the structure-performance interrelationship study of heteroatoms co-doped porous carbon for energy applications.

某些预想的概念验证反应虽可能产生具有新功能或新应用潜力的材料,但最终常被证明是不可实现的或从商业角度上是不可行的。为了在溶剂环境中探索未知反应的反应条件,科研人员已付出了大量的努力,也浪费了大量的精力。因为人们普遍相信通过将反应物溶解在溶剂中,可以提高反应物的活性,从而促进反应。本研究发现了一个反常现象:在不同溶剂环境下,1,3,5-三(氯甲基)-2,4,6-三甲基苯与三聚氰胺的共聚反应都是无法实现的,然而利用无溶剂法却可成功地实现该反应。通过第一性原理计算和分子动力学模拟,证明了溶剂反应不具备的两个决定性因素,即由副产物的及时释放所推动的反应平衡和活化单体分子在固相中的受限热运动却可基于无溶剂法实现。由于具有较高的芳香性和氮杂环含量,由无溶剂法得到的共聚物表现出良好的应用潜力,可作为制备氮掺杂多孔碳的前驱体,使氮掺杂多孔碳具有令人满意的碳产率、理想的残氮含量、理想的结构特性,与最近报道的其他代表性同类吸附剂相比,在二氧化碳捕获能力方面展现出竞争潜力。
