Synthesis and Characterization of A New ㅠ-Conjugated Polymer with Cyanoacrylate Side Chain for Organic Thin Film Transistors |
| 초록 |
A new copolymer, PCCNT with cyanoacrylate, was synthesized by Stille coupling reaction for p-type semiconductors in OTFTs. FTIR and 1H NMR spectroscopes confirmed the structure of PCCNT. The molecular weight of polymer was 14.6 kDa with polydispersity index of 1.72 using GPC. The obtained polymer with long alkyl side chains has good solubility. PCCNT has good thermal stability of (Td = 324 ℃) as well as good oxidation stability with HOMO level of -5.35 eV. UV-vis absorption maximum of the polymer was found at 431 nm in solution and at 444 nm for the film, respectivey. In the photoluminescence (PL), the large red-shifted from solution emission at 493 nm (in solution) to film emission at 539 nm was observed due to intermolecular interaction. The fabricated bottom gate–top contact organic thin film transistors (OTFTs) showed field-effect mobility of 9.02 x 10-5 cm2/Vs and threshold voltage of -3 eV. |
