In this paper we report on the preparation of calix[8]arene functionalized polyglycerol nanogels by miniemulsion polymerization. The gel macromonomers were prepared by anionic ring-opening multibranching polymerization of glycidol using calix[8]arene as initiator. 1,1 ,3,3,3 ,3 -hexamethyl-2,2 -indotricarbocyanine iodide (HITC) red fluorescent dye was used as a guest molecule. Photobleaching up...

quantum chemical calculations, based on density functional theory (dft) method, were performed on calix[4]arene and polychlorinated dibenzo-p-dioxins (pcdds) in gas and liquid phases for comparison purposes. the simulation results show the 1,2,3,4, 6,7,8,9-octachlorodibenzo-p-dioxin (ocdd) is quite a reactive dioxin. this paper attempts to examine the possibility of dioxin adsorption by calix[n...

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 series of calix[4]arene-supported Ln(III)(6) clusters have been synthesised under facile bench top conditions. The magnetic and structural properties of these clusters are reported, the latter suggesting that the Ln(III)-calix[4]arene moiety may be used for the construction of other assemblies in a manner akin to that for the Mn(III)-calix[4]arene analogue.

Calix[4]-bis-2,3-naphtho-crown-6 can be used to discriminate between methylammonium and other organic ammonium ions. An electrode based on this ionophore, potassium tetrakis(p-chlorophenyl)borate (20 mol% relative to the ionophore) as an ionic additive and bis(2-ethylhexyl) sebacate as a solvent mediator in a poly(vinyl chloride) membrane matrix, displayed higher selectivity for methylammonium ...

Cationic calix[6]arene and calix[4]arene derivatives non-covalently bind into a DNA minor groove or RNA major form tweezer-like complexes with nucleotides.

In the title compound, C(90)H(120)O(18)·2CH(3)CN, the calix[6]arene has a 1,2,3-alternate conformation and possesses inversion symmetry. It crystallizes as an acetonitrile disolvate, with a half-mol-ecule of calix[6]arene and one mol-ecule of solvent in the asymmetric unit. In the crystal, the two solvent mol-ecules are enclosed in voids between the calix[6]arene mol-ecules. They form weak C-H⋯...

A photoresponsive ion carrier based on calix[4]arene was synthesized for the control of Na+ flux across lipid bilayer membranes by visible light. Calix[4]arene was chosen as a basic skeleton of a photoresponsive ion carrier because its ether derivatives are known to act as Na+ ion carriers in lipid bilayer membranes. For the synthesis of a photoresponsive carrier, dimethylaminoazobenzene was in...

For the surface-optoelectronic study of Saxitoxin sensing, we fabricated selfassembled calix[4]arene derivative monolayers as the recognition-functional interfaces on a gold surface. An interaction study between Saxitoxin and calix[4]arene derivative monolayers were performed using surface plasmon resonance (SPR) spectroscopy. Among three calix[4]arene derivatives, calix[4]arene crown ether SAM...
