摘要

Reaction of the oligo(phenylenevinylene) 4,4'-bis(2,5-dimethylstyryl)biphenyl (bdb) with CF3CO2Ag in benzene gave a novel octanuclear sandwich cluster [Ag8(bdb)2(C6H6)2(CF3CO2)8]·2C6H6(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℃ and the coordinated benzene molecules at 180℃. In solid state, cluster 1 exhibits fluorescence, and the emission band is red-shifted compared with that of free ligand bdb.
