چکیده
Triptycene-based macrotricyclic host containing two dibenzo-30-crown-10 moieties could form ladder-like supramolecular poly[3]pseudorotaxanes with π-extended viologens in both high concentration solution and solid state.

Triptycene-derived macrotricyclic polyether containing an anthracene unit as a powerful host for 1,2-bis(pyridium)ethane, diquat and 2,7-diazapyrenium salt.
Triptycene-derived macrotricyclic polyether containing an anthracene unit is a powerful host for 1,2-bis(pyridium)ethane, diquat and 2,7-diazapyrenium salt with association constants of the 1 : 1 complexes at >10(5) M(-1). Crystal structures showed that π-π stacking interactions between the host and the guests play an important role in the formation of the stable complexes.
متن کاملA bifunctionalized [3]rotaxane and its incorporation into a mechanically interlocked polymer.
A novel bifunctionalized [3]rotaxane based on a triptycene-derived macrotricyclic host was conveniently synthesized. On the basis of the [3]rotaxane, a linear main-chain poly[3]rotaxane was further obtained by the highly efficient Huisgen 1,3-dipolar cycloaddition.
متن کاملP=O functional group-containing cryptands: from supramolecular complexes to poly[2]pseudorotaxanes.
Two types of cryptand-based host-guest complexes were constructed successfully, in which P=O functional groups were located at the different positions of the third arms. Consequently, supramolecular poly[2]pseudorotaxanes with almost linear and zigzag shapes were formed in the solid state.
متن کاملPseudorotaxanes and Supramolecular Polypseudorotaxanes Based on Dibenzo-24-Crown-8/Paraquat recognition motif
By preparation and characterization of a series of pesudorotaxanes based on DB24C8 and paraquat derivatives, it was found that these complexes were stabilized by N⋅⋅⋅O interactions, C-H⋅⋅⋅O hydrogen bonding, and face-to-face π-stacking interactions. Because methyl protons of paraquat are involved in hydrogen bonding to the host, the substitution of any methyl hydrogen on paraquat causes apparen...

A supramolecular poly[3]pseudorotaxane was prepared by self-assembly of a homoditopic cylindrical bis(crown ether) host and a bisparaquat derivative in solution by host-guest complexation.
