Formation of a [2]pseudorotaxane based on a pillar[5]arene and a rigid guest in solution and in the solid state.
A pillar[5]arene with mono(ethylene oxide) substituents could form a highly stable [2]pseudorotaxane with a rigid guest both in solution and in the solid state.
متن کاملPhotoreversible switching of the lower critical solution temperature in a photoresponsive host-guest system of pillar[6]arene with triethylene oxide substituents and an azobenzene derivative.
A new water-soluble thermoresponsive pillar[6]arene with triethylene oxide groups was synthesized. The pillar[6]arene showed lower critical solution temperature behavior in aqueous solution. Its clouding point was photoreversibly switched based on a photoresponsive host-guest system. The trans form of an azobenzene guest formed a stable 1:1 complex with the pillar[6]arene. Complexation increase...
متن کاملSelective complexation of n-alkanes with pillar[5]arene dimers in organic media.
A pillar[5]arene dimer was synthesized by linking a mono-hydroxylated pillar[5]arene with 1,4-bis(bromomethyl)benzene. The pillar[5]arene dimer formed stronger complexes with n-alkanes than did a monomeric pillar[5]arene.
