摘要
Linking a calix[4] pyrrole anion recognition subunit to chromophores or fluorophores via an alkynyl spacer attached to a beta-pyrrolic position of a calix[4] pyrrole core produces a new class of anion sensor that permits the detection of halide and phosphate anions in organic media via direct, so-called "naked-eye" visualization or fluorescence quenching-based spectroscopic means.
