Highlights

•

We have synthesized a new calixarene based receptor 3 for Cu²⁺.

•

3 Showed ratiometric changes with Cu²⁺ in emission spectrum.

•

Reference compound 4 showed quenching with Cu²⁺ in emission spectrum.

•

Importance of calix[4]arene platform in ion recognition.

Abstract

Synthesis and spectroscopic evaluation of compounds 3a, 3b and 4 reveal that cone conformer of 25,27-bis(o-aminothiophenyl propyloxy) -tetra-p-tert-butylcalix[4]arene 3a can function as a highly selective ratiometric and colorimetric fluorescence probe for copper ions.
