摘要

Abstract

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 LiClO

/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 mg⋅mL

−1

and the number average molecular weight is 35300 with a polydispersity index of 1.65. The side chains on C

position of the monomer maintain unchanged after 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 Mn

and Fe

while fluorescence enhancement for Cr

ions.
