[2]catenanes were investigated, which reveal that incorporation of calix[4]arene into the tetracationic cyclophane reduces pi-stacking interactions between the donor and acceptor units and catenation has substantial influence on conformational distributions of the calix[4]arene moiety. The results demonstrate the versatility of calix[4]arenederivatives as building blocks in the construction of supramolecular

1-bi-2-naphthol-derived calix[4]arene (1) was synthesized via a click reaction. Fluorescence spectra and dynamic light-scattering revealed that Cu(II)–1 complexes were generated in situ and exhibited remarkable enantioselectivity toward mandelicacid. Using this dynamic light-scattering technique, the detection sensitivity was improved almost 100-fold, with a detection limit of 2.0 × 10–7 M, compared
of the interior surface of nanochannels with functional molecules may provide a highly efficient means to control ionic or molecular transport through nanochannels. Herein, we have designed and prepared a aldehyde calix[4]arene (C4AH), which was attached to the interior surface of a single nanochannel by using a click reaction, and that showed a high response for arginine (Arg). Furthermore, the nanofluidic

A novel and sensitive fluorescence sensor has been designed by click chemistry. Based on the obvious and selective fluorescence quenching of anthryl calix[4]arene, a sensitive and robust platform were developed for visual detection of picric acid (TNP) in the mixture of nitro aromatics. The computational calculations revealed the formation of host-guest complex driven by pi-pi stacking interactions. (C) 2013 Elsevier Ltd. All rights reserved.
