Poly(1,4-bis((E)-2-(3-dodecylthiophen-2-yl)vinyl)benzene) for Solution Processable Organic Thin Film Transistor

H-NMR, IR andelemental analysis. The polymer was soluble in specific organic solvent. The weight-average molecularweights (MW) of polymer was found to be 11,000 with polydispersity of 1.82. UV-Visible absorption spectrumshowed the maximum absorption at 428 nm (in solution) and 438 nm (in film). The highest occupied molecularorbital (HOMO) energy of the polymer is −5.36 eV by measuring cyclic voltammetry (CV). A solution-processed polymer thin film transistor device shows a mobility of 8.59 × 10
