Towards this goal, we synthesized two distinct crosslinked ligand dimers, each containing thermolabile tertiary carbamate linkages (Fig. ). The lengths of both crosslinkers were designed to span the short ~7 Å interligand distance down the pore channel of Mg2dotpdc (Fig. ). The ligand dimer L1 is constructed from N-aryl carbamate linkages, which should produce arylamines after thermolysis. In contrast, L2 contains Nalkylcarbamate linkages, which should template more nucleophilic alkylamine pairs. Both ligand dimers were synthesized in 4-5 steps in good overall yield (42-60%, see SI for experimental details).
