摘要
High-quality poly（N-（9-fluorenylmethoxycarbony）-glycine） （PFG）, a new kind of soluble polyfluorene deriva- tive, was successfully synthesized electrochemically by direct anodic oxidation of N-（9-fluorenylmethoxycar- bony）-glycine （FG） in boron trifluoride diethyl etherate （BFEE）. The onset oxidation potential of FG in BFEE was only 0.6 V vs. Pt, which was much lower than that in acetonitrile ＋0.1 mol/L tetrabutylammonium tetrafluoro- borate （TBATFB）. PFG film obtained from BFEE showed good electrochemical activity and thermal stability. It in- dicates that BFEE is a better medium for the electrosynthesis of PFG film. PFG is highly soluble in common or- ganic solvents, facilitating potential applications as a blue-light-emitting material. Fluorescent spectra revealed that PFG was a good blue-light emitter. Results of FT-IR and IH NMR spectra indicated the polymerization location of N-（9-fluorenylmethoxycarbony）-glycine occurred mainly at C（2） and C（7） positions of the fluorine ring.
