High‐quality poly( N ‐(9‐fluorenylmethoxycarbony)‐glycine) (PFG), a new kind of soluble polyfluorene derivative, was successfully synthesized electrochemically by direct anodic oxidation of N ‐(9‐fluorenylmethoxycarbony)‐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 tetra?uoroborate (TBATFB). PFG film obtained from BFEE showed good electrochemical activity and thermal stability. It indicates that BFEE is a better medium for the electrosynthesis of PFG film. PFG is highly soluble in common organic 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 1 H NMR spectra indicated the polymerization location of N ‐(9‐fluorenylmethoxycarbony)‐glycine occurred mainly at C(2) and C(7) positions of the fluorine ring.
