a, PXRD patterns (Cu Kα, intensity profiles above 7° are scaled by two times to show details). b, Scanning electron microscopy (SEM) images showing the same size and hexagonal morphology of ECNU-45 and ECNU-46. c, A molecular structure of the OSDA (TDDH) where C atoms are in grey and N atoms are in light blue. H atoms are omitted for clarity. d, The liquid-state 13C NMR spectrum of the OSDA (bottom) and the solid-state 13C NMR spectrum of ECNU-45 (top). The similar chemical shifts of the bottom and top spectra indicate that TDDH molecules were intact in the structure of ECNU-45.
