Combination of chemical and structural stability by the multiple linker approach. PXRD patterns (a) and N₂ isotherms (b) of 3 A i) after activation at 70 °C for which 1 collapses (Figure 2 a, i) and ii) after treatment with water at RT followed by activation with SCO₂ for which 2 is not stable (Figure 2 c, ii). c) Comparison of BET surface areas of 1, 3 A, 3 B, and 2 before (white) and after (red) water treatment at room temperature. The yellow area highlights the optimum behavior of 3 A, which retains the same BET surface area after water treatment, unlike single linker 2 and multilinker 3 B with higher ptba content.
