چکیده

A calix[4]arene acetylene (C4AE)-modified gold surface is successfully constructed in situ via click chemistry. The functionalized surface is used for selective recognition of paraquat by a wettability switch. Impedance measurements showed that the surface also expresses recognition for paraquat with a high sensitivity of 10 pM. The recognition mode, based on host-guest inclusion, is studied by computational calculations and the possible mechanism is analyzed.

DFT Study of Hydrogen Bonding on Calix[8]arene as Nanostructure Compound

An azobenzene bridge was introduced into the lower (or smaller) rim of p-tert-butylcalix[8]arene to form 1,5-singly bridged calix[8]arene derivatives, respectively. Bridged calix[8]arene of conformationally rigid wereisolated. The stability of the two structures of bridged calix[8]arenes have been compared.The study of organicstructure to form nanoporous structures is a well known in chemistry ...

Development of Conductometric Sensor Based on 25,27-Di-(5-thio-octyloxy)calix[4]arene-crown-6 for Determination of Ammonium

The conductometric sensor based on 25,27-di-(5-thio-octyloxy)calix[4]arene-crown-6 was developed for the quantitative analysis of ammonium. The calixarene was immobilized on the surface of the planar interdigitated electrodes by attachment of its dialkyl sulfide groups to the surface of the gold electrodes. The intrinsic ability of the calixarene to capture ammonium was studied in the conductom...
