Conformationally flexible calix[4]arene chromoionophores: optical transduction of soft metal ion complexation by cation–π interactions

Abstract

Soft metal ions like Pb2+, Cd2+, and Cu2+ form partial-cone complexes with a flexible calix[4]arene chromoionophore in which cation–π interactions cause a bathochromic shift of the UV/Vis absorption maximum.
