摘      要：Synthesis and electrochemical polymerization of 9,9-bis（2-（2-（2-methoxy ethoxy）ethoxy）ethyl）-fluorene （EO-F） into poly[9,9-bis（2-（2-（2-methoxy ethoxy）ethoxy）ethyl）-fluorene] （EO-PF） films are reported. The boron trifluoride diethyl etherate electrolyte enables facile preparation of EO-PF films at lower potential compared to LiCIOa/MeCN and the electrochemical polymerizations are discussed. The EO-PF shows good electrochemical behavior and can be dissolved in solvents such as DMSO and THF. The solubility of EO-PF in THF is 2 ***-1 and the number average molecular weight is 35300 with a polydispersity index of 1.65. The side chains on C9 position of the monomer maintain unchanged aRer electrooxidation into corresponding polymer. The EO-PF dissolved in THF under 365 nm ultraviolet light is sky blue light emitting with the Commission Internationale de L＇Eclairage-CIE coordinates of （0.19, 0.15）. The electropolymerized EO-PF is used for the first time in chemosensing metal ions, demonstrating fluorescence quenching for Mn2＋ and Fe3＋ while fluorescence enhancement for Cr6＋ ions.
