a DSC scans of crystalline HOF-SXU-8 (Red curves represent the first heating and cooling cycle, blue curves represent the second cycle). b Enlarged Figure of the circled part in Fig. 2a. c PXRD patterns of HOF-SXU-8 and HOF-g. d FTIR spectra of HOF-SXU-8 and HOF-g. e SEM image of the HOF-SXU-8 pellet. f SEM image of the HOF-g. g Optical photographs of crystalline HOF-SXU-8 after treated at different temperatures. The sample was put on the mark “X” to assess the variation in transparency.
