Self-assembly of octacyano-biscavitand by metal ligand interaction: incorporation of container unit in polymer back bone

Octacyano-biscavitand 2 was synthesized and the formation of its self-assembled oligomeric coordination molecular capsule 4 with Pd(dppp)OTf2 was studied by 1H NMR, PGSE NMR, and SEM. Oligomeric capsule 4 having container units in the backbone was chopped down to hetero-coupled biscapsules 5 by pyridinocavitand 3.
