No full textDitopic N-donor ligands with terminal 4-pyridyl groups are omnipresent in coordination-based selfassembly.
The utilization of ligands with 3-pyridyl donor groups is significantly less common, because
the intrinsic conformational flexibility of these ligands tends to favor the formation of small aggregates.
Here, we show that large Pd6L12
12+ cages can be obtained by reaction of Pd(II) salts with metallo-ligands
L bearing terminal 3-pyridyl groups. The easy-to-access metallo-ligands contain an Fe(II) clathrochelate
core. These sterically demanding clathrochelate complexes prevent the formation of smaller aggregates,
which is observed for less bulky analogous building blocks. The cages were shown to bind BF4
and
BPh4
anions in aqueous solvent mixtures, whilst the lateral size of the clathrochelate significantly affects
their guest encapsulation behavior.peerReviewe
