Synthesis and X-ray crystal structure of a difunctionalized pillar[5]arene at A1/B2 positions by in situ cyclization and deprotection.
The reaction of 1,4-dimethoxybenzene and paraformaldehyde using AlBr(3) yields multiple-deprotected pillar[5]arenes. A1/B2 di-deprotected pillar[5]arene can be isolated by silica gel chromatography and washing procedures. The X-ray structure and polymerization of the A1/B2 di-deprotected pillar[5]arene are reported.
متن کاملReversible and contrasting changes of the cloud point temperature of pillar[5]arenes with one quinone unit and tri(ethylene oxide) chains induced by redox chemistry and host-guest complexation.
A new water-soluble redox-active pillar[5]arene was synthesized by incorporation of one benzoquinone unit. The pillar[5]arene showed redox-responsive reversible lower critical solution temperature changes in aqueous solution.
متن کاملIncorporation of an A1/A2-difunctionalized pillar[5]arene into a metal-organic framework.
An efficient synthetic route to an A1/A2-difunctionalized pillar[5]arene containing resolvable planar chirality has been developed and the arene employed as a strut in the synthesis of P5A-MOF-1, which has been demonstrated by X-ray powder diffraction analysis--supported by modeling--to be isoreticular with MOF-5. This metal-organic framework has an active domain that expresses good and selecti...
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.
متن کاملMonofunctionalized pillar[5]arenes: synthesis and supramolecular structure.
The first synthesis of a monohydroxy pillar[5]arene has been carried out, by controlling the de-O-methylation of per-methylated pillar[5]arene. Using monohydroxy pillar[5]arene as an intermediate, mono-guest-functionalized pillar[5]arene was prepared. It formed a self-inclusion complex in CDCl(3) whereas in acetone-d(6) dethreading of the guest moiety took place.
