Reaction of the oligo(phenylenevinylene) 4,4′‐bis(2,5‐dimethylstyryl)biphenyl (bdb) with CF 3 CO 2 Ag in benzene gave a novel octanuclear sandwich cluster [Ag 8 (bdb) 2 (C 6 H 6 ) 2 (CF 3 CO 2 ) 8 ]·2C 6 H 6 ( 1 ). The clusters are packed on each other through strong π‐π interactions to form 1D ′brick′ chains, between which the solvated benzene molecules are located. TG analysis showed that cluster 1 could completely liberate the guest benzene molecules at 105 °C and the coordinated benzene molecules at 180 °C. In solid state, cluster 1 exhibits fluorescence, and the emission band is red‐shifted compared with that of free ligand bdb.
