摘要
Sensitive molecular scaffold : The exceptional π-electron-acceptor strength of HAT(CN)6 renders it an excellent colori-metric 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. © 2010 Wiley-VCH Verlag GmbH & Co. KGaA, Weinheim.
