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...

In the title compound, C(6)BrF(4)NO(2), the nitro group is twisted by 41.7 (3)° with reference to the arene ring mean plane. The main inter-actions stabilizing the crystal structure include O⋯Br contacts [3.150 (2) and 3.201 (2) Å], while F⋯F inter-actions are minor [2.863 (3)-2.908 (3) Å].

The selective monoalkylation at the smaller (lower) rim of the p-tert-butylcalix[4]- and -[6]arenes using bis(butyltin)oxide and different alkylating agents is described. The procedure is remarkable for the mild conditions used allowing an efficiently access to monoalkylated calixarene derivatives in moderate to good yields. Monoalkynylcalix[4]arene and monoalkynylcalix[6]arene have been synthe...

We have synthesized a pillar[6]arene in high yield and a co-pillar[6]arene using chlorocyclohexane as a solvent.

Triphosphine and diphosphine ligands with backbones designed to facilitate metal-arene interactions were employed to support multinuclear Ni complexes. Di- and trinuclear metal complexes supported by a triphosphine containing a triarylbenzene linker display diverse metal-arene binding modes. Multinuclear Ni halide complexes were isolated with strongly interacting metal centers bound to opposite...

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⋯...

Calix[8]arenes of conformational rigid were isolated. The NMR parameters of the structure of calix[8]arenes have been compared. The study of organic structures to form nanoporous materials is well-known in chemistry phenomena to find the crystal form of calix[8]arene as supramolecule. Investigated and compared hydrogen bonding, oxygen and nitrogen atoms effect on calix[8]arene and its complexes...

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...
