- Abstract
- We have designed and synthesized the novel p-type polymer containing thienothiophene, thiophene and fluorene with OTFT characteristics. The polymer was synthesized by the palladium catalyzed Suzuki coupling reaction with thienothiophene derivatives, thiophene derivatives and fluorene derivatives. The obtained PTT2BTF can dissolve in common organic solvents such as toluene, THF, chloroform, chlorobenzene and dichlorobenzene. PTT2BTF has a number average molecular weight (M-n) of 25,000 with a poly dispersity index (PDI) of 1.66. PTT2BTF showed good thermal stability with high T-d of 407 degrees C. The OTFT characteristics of the polymer (PTT2BTF) were fabricated. Organic semiconductor was found to exhibit typical p-channel FET characteristics with a hole mobility of 6.3 x 10(-5) cm(2)/Vs and a threshold voltage of -4 V.
