Qian-Rui told me the ingenious weaving path of EMACs he used. I made a schematic plot to show his weave path in the following figure. This path has a major difference from the ones we used for fullerenes before. I.e. one used only one end of fishing thread to weave pyridyl groups (hexagons, green) in the ligands. In doing so, he can weave the whole structure with only one long minimal fishing thread.
