The carbamates in 2-XL-23% could be cleaved via either microwave heating or conventional heating in the solid state under flowing N2. Similar conditions have been previously used to remove tert-butoxycarbonyl (Boc) protecting groups in MOFs. Heating samples of 2-XL-23% at 250 °C for two days under flowing N2 resulted in clean conversion to 2-CH2NH2-23%. Like 1-NH2-18%, no loss in crystallinity was observed (Fig. ), and the BET surface area increased from 2400 m 2 /g to 2610 m 2 /g (Fig. ). Digestion 1 H NMR analysis confirmed quantitative crosslinker removal and the clean conversion of L2 to two equivalents of H4dotpdc-CH2NH2 (Fig. ).
