Abstract / Bemerkung
A new C3v-symmetrical tribenzotriquinacene (TBTQ) derivative bearing six 8-quinolinyloxymethyl units at the rim of the bowlshaped molecular framework is synthesized in a single-step by six-fold etherification of the corresponding hexakis(chloromethyl)-TBTQ precursor with 8-hydroxyquinoline. The resulting compound acts as a fluorescence chemosensor, producing a ` turn-off' fluorescent quenching response in the presence of Ag+ ions, and is highly selective toward Ag+ over other cations, such as Al3+, Ca2+, Cd2+, Co2+, Cr3+, Cu2+, Fe3+, Ga3+, Hg2+, In3+, K+, Mg2+, Mn2+, Na+, Ni2+, Pb2+, Pd2+, and Zn2+. The fluorescence intensity change of the chemosensor solution can be clearly observed by the naked eye upon addition of silver salts.
