Ion sensing of sister sensors based-on calix[4]arene in aqueous medium and their bioimaging applications

Malak Alizada et al.

Summary: In this study, sister calix[4]arene derivatives with two NBD units were successfully synthesized as sensors for selective ion detection. The sensors showed excellent on-off fluorescence response towards Cu2+ cations and H2PO4- & F- anions in aqueous solution, with high selectivity and low detection limits. These compounds can be used for identifying specific ions in living cells through confocal microscopy.

Synthesis of calix[4]arenes bearing thiosemicarbazone moieties with naphthalene groups: Highly selective turn off/on fluorescent sensor for Cu(II) recognition

Cinthia Quiroga-Campano et al.

Summary: Calix[4]arenes-based fluorescent chemosensors containing thiosemicarbazone and naphthalene were synthesized and examined for their binding abilities towards anions and cations. Both receptors showed selective recognition of Cu(II) and exhibited an off/on fluorescence behavior due to complex formation with copper. The H-1 NMR spectra indicated that receptor L2 changed its conformation from cone to pinched cone upon interaction with copper.
