a Synthetic route of Ce-2,3,6,7,10,11-hexahydroxytriphenylene (Ce-HHTP) via the one-step hydrothermal reaction of H6HHTP with hydrated Ce(NO3)3 and structure of Ce-HHTP. Atoms are colored as follows: O (red), C (black), Ce (light blue), and H (white). b, c Scanning electron microscopic (SEM) images of Ce-HHTP. d Transmission electron microscopic (TEM) image of Ce-HHTP. e Powder X-ray diffraction (PXRD) pattern and the Rietveld refinement of Ce-HHTP. f Energy-dispersive X-ray spectroscopy (EDS) elemental mappings of Ce-HHTP.
