The adsorption of pyrazolone(HPMSP), Calix[4]-arene,Cu and Cs, on carbon nanotube(CNT) atroom temperature has been investigated using spectroscopy.Uv spectroscopy indicated that pyrazolone molecules adsorbed on carbon nanotube at roomtemperature in compared calix[4]- arene molecules adsorbed approximately same.The amount ofpyrazolone(HPMSP) adsorb 3.8. le mol/g and amount calix[4]-arene adsorbe...

The R2PI-TOF spectra of supersonically expanded rare gas/chiral arene heteroclusters have been rationalized in terms of the distortion of the pi-electron density reflecting the different dipole and quadrupole momenta induced in the rare gas atoms by interaction with the opposite pi-faces of the chiral arene itself.

Reduction of [U(Ts(Tol))(Cl)(μ-Cl)U(Ts(Tol))(THF)2] [2, Ts(Tol) = HC(SiMe2NAr')3; Ar' = 4-MeC6H4)] with KC8 in toluene afforded the new arene-bridged diuranium complex [{U(Ts(Tol))}2(μ-η(6):η(6)-C6H5Me)] (3); combined structural, spectroscopic, magnetic, and computational analyses unambiguously confirm that the uranium centres in 3 are in the +5 oxidation state and the toluene is a 10π-tetraanion.

The effects of introducing bpy ligands with CH 2 CCH substituents in the 6- and 6,6′-positions [Cu(N^N)(P^P)] + complexes are explored; structural data discussed terms CC⋯π arene interactions compounds Cambridge Structural Database.

The reaction of [(arene)RuCl2]2 (arene /C6H6, p -Me /C6H4 / i Pr, C6Me6) with p -thiocresol, 2-mercaptoethanol and p mercaptophenol in refluxing ethanol gives the tris-thiolato complexes [(arene)2Ru2(SR)3] (R /p -C6H4 /Me, CH2CH2OH, p C6H4OH) which can be isolated as the chloride salts. The remarkable selectivity of (arene)ruthenium units for SH versus OH functions reflects the affinity of ruth...

A series of pentanuclear Ln(III) clusters, [Ln5(μ4-OH)(μ3-OH)4(L1)(acac)6] (H4L1 = p-tert-butylthiacalix[4]arene; acac = acetylacetonate; Ln = Dy, Ho, Er) and [Ln5(μ5-OH)(μ3-OH)4(L1)(L2)2(acac)2(CH3OH)2] (H3L2 = 5,11,17,23-tetrakis(1,1-dimethylethyl)-25,26,27-trihydroxy-28-methoxy thiacalix[4]arene; Ln = Dy, Ho, Er), have been synthesized based on the thiacalix[4]arene ligand. All of these comp...

Driven by an interest in the impact of para-substituent calix[4]arenes on metal complexation and structural chemistry, studies p-cyclohexylcalix[4]arene (L) have been carried out. The 1:1 dichloromethane dimethylformamide solvates were found to be isostructural, different typical bilayer structure often observed for p-t-butylcalix[4]arene solvates. methanol solvate, contrast, does form a bilaye...

A photoactivated ruthenium(II) arene complex has been conjugated to two receptor-binding peptides, a dicarba analogue of octreotide and the Arg-Gly-Asp (RGD) tripeptide. These peptides can act as "tumor-targeting devices" since their receptors are overexpressed on the membranes of tumor cells. Both ruthenium-peptide conjugates are stable in aqueous solution in the dark, but upon irradiation wit...

While a single pillar[6]arene ring, nestling between two cucurbit[6]uril rings in a series of three hetero[4]rotaxanes, is conformationally mobile in solution, it adopts the energetically most favourable conformation with local C3V symmetry in the solid state.

Two neutral macrobicyclic anion receptors 4 and 6, containing a calix[4]arene in the cone conformation, two l-alanine units, and a 2,6-diacylpyridine or a phthaloyl bridge, are described. The x-ray crystal structure of the acetone complexes of the pyridine containing macrocycle 6 shows the four amide NH groups to be in close proximity to the chiral pocket delimited by the pyridine and one aroma...
