Abstract(summary):

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. Highlights • We have synthesized a new calixarene based receptor 3 for Cu 2+ . • 3 Showed ratiometric changes with Cu 2+ in emission spectrum. • Reference compound 4 showed quenching with Cu 2+ in emission spectrum. • Importance of calix[4]arene platform in ion recognition.
