The luminescent polymer, F‐DMBN, containing 2,2′‐dimethacrylanido‐1,1′‐binaphthyl (DMBN) and 9,9‐diphenylfluorene, is synthesized by the Heck reaction of halogenated and olefinic monomers. The structures are characterized by MS, 1 H‐NMR, and IR, and the photoluminescent properties are investigated by UV/vis absorption and fluorescence spectra. The results show that the polymer emits blue and blue–violet light. The luminescence quantum yield is 0.424 in ethanol and the emission spectra exhibit obvious solvent effects. In addition, the light emitting can be quenched by both electron donor ( N , N ‐dimethylaniline) and electron acceptor (fullerene), where the processes follow the Stern–Volmer equation. Moreover, the interaction between F‐DMBN and carbon nanotubes is also studied by fluorescent quenching. © 2005 Wiley Periodicals, Inc. J Appl Polym Sci 98: 434–438, 2005
