A series of N,N'-bis(pyridylmethyl)-diaminoalkanes have been synthesized from 2,3 or 4-pyridinecarboxaldehyde and different diamines. The possibility of self-assembly psedorotaxanes of cucurbit[n=5~8]urils with rod materials has been investigated by using NMR techniques. Here the rod materials or guests are polyamines of N,N'-bis(pyridylmethyl)-diaminoalkane. The structures of the host-guest complexes of the cucurbit[n=5~8]urils with the rods were discussed in details. The experimental rsults revealed that different interaction models could be formed from different cucurbit[n=5~8]urils and different N,N'-bis(pyridylmethyl)-diaminoalkanes, also multiple interaction models could be formed from a certain cucurbit[n]uril and a certain N,N'-bis(pyridylmethyl)-diaminoalkane. These suggestions for the interaction models were supported by the ESMS spectroscopy.
