New amorphous semiconducting copolymers, poly(9,9-dialkylfluorene)-alt-(3- dodecylthienyl-divinylbenzene-3dodecylthienyl) derivatives (PEFTVB and POFTVB), were designed, synthesized, and characterized. The structure of copolymers was confirmed by H NMR, IR, and elemental analysis. The copolymers showed very good solubility in organic solvents and high thermal stability with high T g of 178-185 °C. The weight average molecular weight was found to be 107,900 with polydispersity of 3.14 for PEFTVB and 76,700 with that of 3.31 for POFTVB. UV-vis absorption studies showed the maximum absorption at 428 nm (in solution) and 435 nm (in film) for PEFTVB and at 430 nm (in solution) and 436 nm (in film) for POFTVB. Photolumineseence studies showed the emission at 498 nm (in solution) and 557 nm (in film) for PEFTVB and at 498 nm (in solution) and 536 nm (in film) for POFTVB. The solution-processed thin-film transistors showed the carrier mobility of 2 × 10-4 cm2 V -1 s-1 for PEFTVB-based devices and 2 × 10 -5 cm2 V-1 s-1 for POFTVB-based devices.

New semiconducting polymer, poly[1,4-bis((E)-2-(5-bromo-3-dodecylthiophen- 2-yl)vinyl)benzene], was designed, synthesized and characterized. The structure of polymer was confirmed by 1H-NMR, IR and elemental analysis. The polymer was soluble in specific organic solvent. The weight-average molecular weights (MW) of polymer was found to be 11,000 with polydispersity of 1.82. UV-Visible absorption spectrum showed the maximum absorption at 428 nm (in solution) and 438 nm (in film). The highest occupied molecular orbital (HOMO) energy of the polymer is -5.36 eV by measuring cyclic voltammetry (CV). A solutionprocessed polymer thin film transistor device shows a mobility of 8.59 × 10 -4 cm2 V-1 s-1, an on/off current ratio of 2.0 × 104. Copyright
