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.
