A novel ligand: 2,2′‐(1,3‐phenylenedivinylene)bis‐8‐hydroxyquinoline ( m ‐B8QPH) ( 4 ) and the corresponding polymeric metal complex Zn ( m ‐B8QPH ) ( 5 ) were designed and synthesized in a convenient way. The luminescence properties of the compounds Zn ( m ‐B8QPH ) ( 5 ) and Zn( p ‐B8QPH) ( 9 ) were investigated by UV‐vis and fluorescence spectra in DMF at room temperature. The experimental results showed that the polymeric complexes 5 and 9 emitted yellow luminescence at 578 and 554 nm in DMF solution. The polymeric complex 5 has demonstrated good solubility in common organic solvents and good thermal stability with high T g : 261°C. Furthermore, the molecular interactions of 5 with fullerene (C 60 ) and fulleropyrrolidine containing 3,5‐bis(trifluoromethyl)benzene ( 11 ) were also investigated, which indicated the metal dye 5 can be used as new fluorescent probe.
