New Crystal Structures of p-tert-butylthiacalix [6] arene Complexes with Toluene and Benzyl Alcohol

A {Co32} nanosphere supported by p-tert-butylthiacalix[4]arene.

Calixarene-capped Co(32) clusters are constructed by a sodalite Co(II)(24) cage and an encapsulated Co(III)(8) cube. The spherical units are arranged into three isomeric structures, two of which are stacked by the bcc lattices and the third of which is assembled by the cubic closest packing of the spherical units.

Thermodynamic study of dioxovanadium (V) Complexes with p-sulphonato-calix [6] arene in aqueous solution

p-tert-Butylthiacalix[4]arene-supported high-nuclearity {Co24M8} (M=Mo or W) nanospheres and the hybrids with Keggin polyoxometalates.

Two hybrid assemblies (3 and 4) with two kind of nanoscaled cluster units, the spherical [Co(24)(TC4A)(6)(MO(4))(8)Cl(6)](2+) cation (1 and 2) and Keggin-type [PM(12)O(40)](3-) anion (M = Mo (1/3), W (2/4)), were solvothermally prepared and characterized, in which the spherical units are constructed by six Co(4)-p-tert-butylthiacalix[4]arene (Co(4)-TC4A) SBUs linked by eight MO(4) tetrahedrons ...

Cataliticoxidation of benzyl alcohol by Cu(II) polypyridyl complexes

Two polypyridyl copper(II) complexes, [Cu(phen)(phen-dione)Cl]Cl (1) and [Cu(bpy) (phen-dione)Cl]Cl (2), (where Phen =1,10-phenanthroline, bpy =2,2'-bipyridine and Phen-dione = 1,10-phenanthroline-5,6-dione), were used as efficient catalysts for the oxidation of benzyl alcohol to benzaldehyde. The effects of various parameters such as reaction temperature, reaction time, etc. were studied. The ...

Twice as smart behavior of tert-butylthiacalix[4]arene derivative in glassy and crystalline form.

A studied tert-butylthiacalix[4]arene derivative with four N-(2-acetoxyethyl)carbamoylmethoxy substituents on its lower rim in partial-cone configuration (calixarene 1) can remember its previous treatment in three essentially different ways by the formation either of a molecular glass or two metastable polymorphs after heating or the removal of an included guest molecule. Guest-induced memory i...
