2-Bromothiazole (cas: 3034-53-5) belongs to thiazole derivatives. Thiazole is a five-membered, unsaturated, planar, π-excessive heteroaromatic containing one sulfur atom and one pyridine-type nitrogen atom at position 3 of the cyclic ring system. The pyridine-type nitrogen in the thiazole ring deactivates the ring for electrophilic substitution reactions, which is further reduced in acid due to protonation of the thiazole ring.Product Details of 3034-53-5

Achieving high elec. conductivity and thermoelec. power factor simultaneously for n-type organic thermoelecs. is still challenging. By constructing 2 new acceptor-acceptor n-type conjugated polymers with different backbones and introducing the 3,4,5-trimethoxyphenyl group to form the new n-type dopant 1,3-dimethyl-2-(3,4,5-trimethoxyphenyl)-2,3-dihydro-1H-benzo[d]imidazole (TP-DMBI), high elec. conductivity of 11 S cm-1 and power factor of 32μW m-1 K-2 are achieved. Calculations using D. Functional Theory show that TP-DMBI presents a higher singly occupied MO (SOMO) energy level of -1.94 eV than that of the common dopant 4-(1, 3-dimethyl-2, 3-dihydro-1H-benzoimidazol-2-yl) Ph dimethylamine (N-DMBI) (-2.36 eV), which can result in a larger offset between the SOMO of dopant and LUMO (LUMO) of n-type polymers, though that effect may not be dominant. The doped polymer films exhibit higher Seebeck coefficient and power factor than films using N-DMBI at the same doping levels or similar elec. conductivity levels. Also, TP-DMBI doped polymer films offer much higher electron mobility of up to 0.53 cm2 V-1 s-1 than films with N-DMBI doping, demonstrating the potential of TP-DMBI, and 3,4,5-trialkoxy DMBIs more broadly, for high performance n-type organic thermoelecs. In the experiment, the researchers used many compounds, for example, 2-Bromothiazole (cas: 3034-53-5Product Details of 3034-53-5).
