Abstract
We reported the fabrication of conjugated porous polymer films based on 4,4′,4″-Tris(9-carbazolyl)triphenylamine (TCTA) using electrochemical polymerization in CH2Cl2 containing different ratios of boron trifluoride diethyl etherate (BFEE). The oxidation potential of TCTA in CH2Cl2 with 20 vol % BFEE was measured to be only 0.28 V vs. Ag/AgCl, which was lower than that determined in pure CH2Cl2 (0.72 V vs. Ag/AgCl). Also, PTCTA films obtained from this medium showed better electrochemical behavior. And Fourier Transform Infrared spectra were used for structural analysis of polymers. From Scanning Electron Microscopy for surface morphological analysis, we founded that different percentages of BFEE were important in the control of the resulting surface morphology.
