Phenylthiophene (P2PT) has been electrochemically polymerized in pure boron trifluoride diethyl ether (BFEE) solutions or in a com p osite electrolyte of BFEE and trifluoroacetic acid (TFA).The addition of a certa in amount of TFA into BFEE lowered the oxidation potential of the monomer,accelerat ed the polymerization and also increased the current efficiency of the electrosy nthesis.The morphology and electrochemical behavior of as\|grown P2PT films were studied by scanning electron microscopy and cyclic voltammetry.Poly(2\|phenylth iophene) in dedoped state is soluble in usual organic solvents such as tetrahydr ofuran and chloroform,etc.Its structure has been examined by infrared,Raman and UV\|visible spectroscopies.The molecular weight of the polymer was measured to b e about 800 Da.Fluorescent spectral studies indicate the polymer is a blue\|gree n light emitter.
