No structural degradation following thermal treatment is observed, as is evident by the powder X-ray diffraction (PXRD) patterns (Fig. ). A large increase in the Brunauer-Emmett-Teller (BET) surface area is observed, from 2130 m 2 /g in 1-crosslinked to 2730 m 2 /g in 1-templated (Fig. ). This latter value is within the range of previously reported surface areas for unfunctionalized Mg2dotpdc (2440-3100 m 2 /g), consistent with full removal of the crosslinker. Cooperative aldol condensation.
