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 1H-NMR and 13C-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.

三氟甲基取代芳族二胺的酶促和化学氧化聚合对热和光物理性质的影响

半导体聚合物已用于一些领域应用,例如涂料、蓄电池、太阳能电池、可充电电池、离子传感器、感光器、发光二极管和电致变色仪器。Poly(TFMBDA)-O和Poly(TFMBDA)-E的Poly(4-(trifluoromethyl)benzene-1,2-diamine)s分别通过化学氧化和酶促聚合方法合成,使用4-(trifluoromethyl)benzene- 1,2-二胺 (TFMBDA) 作为单体。FT-IR、UV-vis 和1 H-NMR 和13使用 C-NMR 仪器以确认所有化合物的结构。根据 GPC 测量,发现聚合物的 Mw 值及其 PDI 值分别在 5000–7000 Da 和 1.045–1.115 之间。聚 (TFMBDA)-O 吩嗪型结构的玻璃化温度高于聚 (TFMBDA)-E,后者由与 –NH 桥连接的苯基单元组成。一旦 Poly(TFMBDA)-O 和 Poly(TFMBDA)-E 被紫外光激发,根据光致发光测量,它们在 DMF 中的紫色光致发光 (PL) 发射的量子效率分别为 6.3% 和 13.7%。SEM 图像显示,Poly(TFMBDA)-O 由大约 1-2 μm 的均匀微球和具有不同孔径的颗粒表面组成。
