Syntheses, structures, luminescence and CO2 gas adsorption properties of four three-dimensional heterobimetallic metal–organic frameworks

From zero-dimensional metallomacrocycle to three-dimensional metal–organic frameworks mediated by solvent polarity: near-white light emissions and gas adsorption properties

“…These results indicate the CO 2 adsorption capacity is relative to the framework stability of MOFs. 23,26 Photoluminescence spectra Solid-state PL spectra of H 2 L1 and H 4 L2 ligands, 0D metallomacrocycle 1, 3D MOFs 3, 5, and 2D Fig. 5 The N 2 gas adsorption-desorption isotherms at 77 K for activated 2-5.…”

“…As shown in Fig. 6, the CO 2 gas adsorption isotherms of the activated 2-5 samples were measured at 273 K. 2 shows a higher CO 2 adsorption capacity of 92.24 cm 3 g −1 (18.44 wt%) at 273 K and P/P 0 = 1.0, whereas 4 reveals relatively low CO 2 adsorption capacity of 33.98 cm 3 g −1 (6.79 wt%) at 273 K and P/P 0 = 1.0, which is probably due to its lower framework stability, 23,26 as indicated by the TGA curve of the activated sample of 4 (Fig. S16, ESI †).…”
