“…Based on the aforementioned values, the T g temperatures of the polymers were found to be lower than the T on temperatures. Also, in previous studies, the T g values of the polymers were reported to be lower than the T on values 52–54 . T g of Poly(TFMBDA)‐O was higher than that of Poly(TFMBDA)‐E.…”

Semi-conductive polymers have been used in a few area applications such as coatings, accumulators, solar cells, rechargeable batteries, ion sensors, photoreceptors, light-emitting diodes and electrochromic instruments. Poly(4-(trifluoromethyl)benzene-1,2-diamine)s of Poly(TFMBDA)-O and Poly(TFMBDA)-E were synthesized via chemical oxidative and enzymatic polymerization methods, respectively, using 4-(trifluoromethyl)benzene-1,2-diamine (TFMBDA) as monomer. FT-IR, UV-vis and 1 H-NMR and 13 C-NMR instruments were utilized in order to confirm the structures of all compounds. The Mw values of the polymers and their PDI values were found to be between 5000-7000 Da and 1.045-1.115, respectively, from GPC measurements. The glass temperature of phenazine-type structure of Poly(TFMBDA)-O was higher compared to that of Poly(TFMBDA)-E, which was composed of phenyl units linked with -NH bridges. As soon as Poly(TFMBDA)-O and Poly(TFMBDA)-E were excited by UV light, they had a quantum efficiency of 6.3% and 13.7%, respectively, in DMF for violet photoluminescence (PL) emission depending on photoluminescence measurement. SEM images revealed that Poly(TFMBDA)-O consisted of approximately 1-2 μm of uniform micro-spheres and a granular surface with different pore diameters. The enzymatic oxidation with HRP afforded Poly(TFMBDA)-E micro-rods of about 5-10 μm-long shape in their SEM images.

[1][2][3] Until now, these class of polymers have attracted much attention owing to its beneficial properties and wide application in numerous fields. In particular, their electronic and optical features can be modified by changing synthetic methods or organic precursors, which are more favorable than inorganic materials. 4,5 Taking into account processing CPs, they are widely used in the production of electronic materials such as conductive coatings, accumulators, solar cells, photoreceptors, rechargeable batteries, photodiodes, electrochromic devices, lightemitting diodes and sensors. [6][7][8] The features of CPs highly depend on the structures of aromatic units along the polymer chains. 9,10 Accordingly, the aromatic units in the main CP chains, which are constructed by a sp 2 carbon framework, encourage the charge transport through the polymer backbones. 11,12 Therefore, the syntheses of new CPs is important in technological implementation. 13,14 Among π-conjugated polymers, poly(phenylenediamine)s are considered to be significant conducting polymers due to its high gas
