摘要

Hierarchical self-assembly of complex supramolecular architectures allows for the emergence of novel properties at each level of complexity.The reaction of the ligand components A and B with Fe" cations generates the[2X_2]grid-type functional building modules 1 and 2,presenting spin-transition properties and preorganizing an array of coordination sites that sets the stage for a second assembly step.Indeed,binding of La~(III)ions to 1 and of Ag1 ions to 2 leads to a ID columnar superstructure 3 and to a wall-like 2D layer 4,respectively,with concomitant modulation of the magnetic properties of 1 and 2.Thus,to each of the two levels of structural complexity generated by the two sequential self-assembly steps corresponds the emergence of novel functional features.
