The π‐Accepting Arene HAT(CN)₆ as a Halide Receptor through Charge Transfer: Multisite Anion Interactions and Self‐Assembly in Solution and the Solid State

Abstract

Sensitive molecular scaffold: The exceptional π-electron-acceptor strength of HAT(CN)6 renders it an excellent colorimetric halide sensor. It engages in multisite anion interactions, namely, both charge-transfer and anion–π, in solution and the solid state. The halide ions are the driving elements for the spontaneous self-assembly of the sandwich-like complexes through η2,η2-charge-transfer contacts.
