Self assembled grid complexes based on hydrazone ligands have a variety of novel properties as a result of the increased acidity of the hydrazone N-H bond upon metal coordination. Recent results with zinc complexes have shown that loss of this proton can result in rotation of intercalated phenyl rings, and under certain circumstances, influence the assembly of the grid complex. In order to further probe inter-ligand interactions in these complexes we report the synthesis of a series of hydrazone ligands with substituted phenyl rings and the effect of these substituents on assembly and solution dynamics of the related grid complexes.
