A family of one-dimensional coordination polymers, [Ag4(O2C(CF2)2CF3)4(phenazine)2(arene) n ]·m(arene), 1 (arene = toluene or xylene), have been synthesized and crystallographically characterized. Arene guest loss invokes structural transformations to yield a pair of polymorphic coordination polymers [Ag4(O2C(CF2)2CF3)4(phenazine)2], 2a and/or 2b , with one- and two-dimensional architectures, r...
Received 08 August 2012, Revised 07 December 2012, Accepted 10 December 2012 -------------------------------------------------------------------------------------------------------------------------------------------Abstract The present study explores the copper selective complexation character of 5,11,17,23-tetranitro25,26,27,28-tetrahydroxycalix[4]arene (p-TNC4) among a series of different al...
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.
Spectropholornetrie technique is used to evaluate binding of the vanadium(1U) ion to a water solublecaruc[4] arene molecule in aqueous solution. On the basis of the calculated value formation constant at25rC.we found that the eomplexation of this metal on is very favored towards 25, 26, 27, 2Stetrahydroxy-5, 11, 17, 23-tetnmulphonalic acid-calix[0]areneGaussian 03 package.
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 long period grating (LPG) modified with a mesoporous film infused with a functional compound, calix[4]arene, was employed for the detection of volatile organic compounds (VOCs). The mesoporous film consisted of an inorganic part, of SiO2 nanoparticles (NPs) along with an organic moiety of poly(allylamine hydrochloride) polycation PAH, which was finally infused with functional compound, p-sulp...
Mesoporous silica nanoparticles (MSNs) have been surface-functionalized with choline moieties encircled by sulfonatocalix[4]arenes. Two enzyme cleavable sites are incorporated in the stalks for specific enzymes to regulate the release of loaded cargos from MSNs. These gated materials show a clear enzymatic response and proven orthogonality.
