Resorcinarenes are hexameric capsules in solution.
The host-guest complexes of resorcin[4]arenes with small molecules in organic solutions are examined using modern NMR spectroscopic methods. The complexation of glutaric acid and beta-methyl d-glucopyranoside in chloroform were investigated through 2D COSY, 2D NOESY, 1D NOE, and diffusion-ordered NMR spectroscopy (DOSY) techniques. These methods indicate that the complex is a self-assembled cap...
متن کاملPhotoresponsive self-assembled hexameric capsules based on calix[4]resorcinarenes bearing azobenzene dendron conjugates as side chains.
We synthesized calix[4]resorcinarenes bearing various azobenzene dendron conjugates as side chains, wherein the azobenzene moiety is a photoresponsive unit and the dendron moiety is a capsule-destabilizing unit, and then studied the photoresponsive properties of their self-assembled hexameric capsules in conjunction with guest encapsulation in H2O-saturated CDCl3. It was found that correlation ...
متن کاملExploring the limits of encapsulation within hexameric pyrogallol[4]arene nano-capsules.
Large fluorescent molecules have been encapsulated in pyrogallol[4]arene nano-capsules, thus exploring the limits of molecular encapsulation; the orientation of these probe molecules within these nano-capsules has been examined with additional computational approaches in one case.

The reaction of tetra-kis-(all-yloxy)calix[4]arene with the first-generation Grubbs catalyst, followed by catalytic hydrogenation, gave the novel bis-calixarene 15,20,46,51,64,69,74,79-octa-oxatridecacyclo[32.28.8.8(3,28).1(13,53).1(22,44).0(9,14).0(21,26).0(38,70).0(40,45).0(52,57).0(59,63).0(7,80).0(32,73)]octa-conta-1(63),3,5,7(80),9(14),10,12,21,23,25,28(73),29,31,34,36,38(70),40,42,44,52,5...
متن کاملSynthesis and structural characterisation of lower rim halogenated pyrogallol[4]arenes: bi-layers and hexameric nano-capsules.
Two lower rim halogenated pyrogallol[4]arenes have been synthesised and structurally characterised as either bi-layer or hexameric nano-capsule motifs depending upon chain length and functionalisation.
