[60]Fullerene hexakisadducts possessing 12 carboxylic acid side chains form crystalline hydrogen-bonding frameworks in the solid state. Depending on the length of the linker between the reactive sites and the malonate units, the distance of the [60]fullerene nodes and thereby the spacing of the frameworks can be controlled and for the most elongated derivative, continuous channels are obtained within the structure. Stability, structural integrity and porosity of the material were investigated by powder X-ray diffraction, thermogravimetry and sorption measurements.
[60]富勒烯六加合物具有12个羧酸侧链,在固态下形成晶体氢键框架。根据反应位点和马隆酸单元之间的连接剂长度,可以控制[60]富勒烯节点的距离,从而控制框架的间距。对于最长的衍生物,结构内获得了连续的通道。通过粉末X射线衍射、热重分析和吸附测量研究了材料的稳定性、结构完整性和孔隙度。
