Abstract

Abstract : The recognition and the chemical-response properties of a bis-acridinium triphenylene receptor were investigated. Abstract : A dicationic receptor based on two acridinium moieties linked by a triphenylene spacer was studied in solution and in the solid state. Recognition moieties, namely acridiniums, were exploited to evidence a host–guest response of the receptor with electron rich guests. Upon addition of methoxide anions, the formation of the bis-acridane form of the receptor was observed. The chemical responsiveness of the receptor to these anions inhibits its recognition properties towards π-donor guests. In addition, the reversibility of the chemical response was demonstrated under acidic conditions.
