A novel carbon material with an ultra-hydrophilic surface and an ordered arrangement of uniformly sized mesopores is synthesized via a solvent-free nanocasting approach conducted in a planetary ball mill. The synthesis involves a mechanochemical coordination reaction of bipyridine and copper chloride and its subsequent carbonization. Stemming from the synergistic effect of uniformly dispersed 34 wt% of heteroatoms and the highly ordered mesoporous structure (specific surface area >1000 m² g⁻¹, pore volume >1.2 cm³ g⁻¹), the apparent water contact angle of the material is 0° – an unprecedented value for carbon materials. This novel type of carbon, with its tailorable pore structure, constitutes an ideal model material for fundamental investigations and can open new perspectives for advanced applications of porous carbons where polar wettability is crucial. Moreover, the solvent-free ball milling synthesis concept paves the way towards many novel materials, that syntheses are currently suffering from solubility issues in the nanocasting process.

球磨机中的纳米铸造–结合了碳材料的超亲水性和有序介孔性†

通过在行星式球磨机中进行的无溶剂纳米浇铸方法，合成了具有超亲水表面和有序排列的均一尺寸的中孔的新型碳材料。该合成涉及联吡啶和氯化铜的机械化学配位反应及其随后的碳化。源于均匀分散的34 wt％的杂原子和高度有序的介孔结构（比表面积> 1000 m ² g ^-1，孔体积> 1.2 cm ³ g ^-1），材料的视在水接触角为0°–对于碳材料，这是空前的值。这种新型的碳具有可调整的孔结构，是进行基础研究的理想模型材料，可以为极性润湿性至关重要的多孔碳的高级应用开辟新的前景。此外，无溶剂球磨合成概念为许多新型材料铺平了道路，目前合成材料正遭受纳米浇铸工艺中的溶解度问题。
