Condensation of an ( S )- or ( R )-BINOL-derived dialdehyde and tris(2-aminoethyl)amine produced chiral [2+3] imine cages, which were further reduced to furnish more stable chiral amine cages and applied in the enantioselective recognition of (1 R ,2 R )- and (1 S ,2 S )-1,2-diaminocyclohexane.

A macro-/mesoporous polymeric network with densely incorporated pillar[5]arene functionality was prepared via ionic complexation between a polymerized ionic liquid and carboxylated pillar[5]arene. It retained the solution-state host-guest property of the pillar[5]arene and was successfully applied as a selective absorbent for n-alklyene diols.

A pillar[4]arene[1]quinone and a difunctionalized pillar[5]arene have been synthesized by partial oxidation.

A novel non-symmetric pillar[5]arene-based anion receptor containing multiple triazole anion-binding sites was designed and synthesized. It has high affinity and selectivity for the fluoride anion.

Four constitutional isomers of BMpillar[5]arene were prepared from 1-butoxy-4-methoxybenzene and they showed different binding abilities with n-octyltrimethyl ammonium hexafluorophosphate.
