In the title compound, [RuCl(C(10)H(14))(C(14)H(16)N(2))]PF(6), the aromatic ring of the isopropyl-methyl-benzene fragment shows an η(6)-arene coordination to the ruthenium atom. Its coordination sphere is completed by a chloride ligand and 2-(sec-butyl-imino-meth-yl)quinoline. The dihedral angle between the η(6)-arene ring and the quinoline Schiff base is 45.64 (9)°. The sec-butyl substituent ...

Nitration of p-tert-butylcalix[n]arene methyl ethers under a variety of reaction conditions has been examined. It has been determined that amongst different nitration procedures adopted (AlCl3/KNO3, HNO3/CH3COOH, HNO3/(CH3CO)2O, cerium(IV) ammonium nitrate/CH3COOH), ipso-nitration with CH3COOH/HNO3 gives best yields of p-nitrocalixarenes and work up conditions. ipso-Nitration of tetramethoxytet...

A novel luminescent inclusion complex, {[(C4AS)(2)Ag(3)(mu-2,2'-bpy)(2)(2,2'-bpy)(2)] [Ag(5)(mu-2,2'-bpy)(4)(2,2'-bpy)(4)].20H(2)O}(n) () (2,2'-bpy = 2,2'-bipyridine, C4AS = p-sulfonatocalix[4]arene), with an unusual framework is reported: the parallel 1D infinite silver(i) chains separated by the water belts reside in the big cavities of the p-sulfonatocalix[4]arene-trisilver blocks.

Two generations of lipophilic pyrenyl functionalized poly(benzyl ether) dendrimers (P(1) and P(2)) have been synthesized. The thermal properties of the two functionalized dendrimers have been investigated, and the pyrenyl group of the dendritic molecules encapsulated in the arene-ruthenium metalla-cage, [Ru(6)(p-cymene)(6)(tpt)(2)(donq)(3)](6+) ([1](6+)) (tpt=2,4,6-tri(pyridin-4-yl)-1,3,5-triaz...

Oxacalix[6]arene vanadium complexes have been employed for the ROP of cyclic esters and ethylene polymerization.

Patterns of noble metal nanoparticles (NMNPs) of ruthenium and platinum are formed on p-phosphonic acid calix[8]arene stabilised graphene in water. This involves hydrogen gas induced reduction of metal ions absorbed on the stabilised graphene, with TEM revealing the patterns being comprised of domains of parallel arrays of NMNPs ∼7 nm apart. The domains are orientated in three directions on eac...

A p-tertbutylcalix[4]arene derivative was synthesized from a reaction of the diisothiocyanate p-tertbutylcalix[4]arene, obtaining crystals that were then characterized by mass spectroscopy, Raman spectroscopy, and single-crystal X-ray diffraction. The molecule presents two acid carbamothioic-n-ethoxy-methyl-ester substituent groups. Through crystallization of this compound, it was also found th...
