N2 - New anthracene-containing conjugated molecules have been synthesized through Stille coupling reaction. 2,6-Dibromo-9,10-bis(4-hexylphenyl)ethynyl) anthracene and 2,6-dibromo-9,10-bis(phenylethynyl)anthracene were reacted with tributyl(5'-hexyl-2,2'-bithiophen-5-yl)stannane to yield 5',5″-(9,10- bis(phenylethynyl)anthracene-2,6-diyl)bis(5-hexyl-2,2'-bithiophene), 1 and 5',5″-(9,10-bis((4-hexylphenyl)ethynyl) anthracene-2,6-diyl)bis(5-hexyl-2, 2'-bithiophene), 2. The molecule, 2 only exhibit good solubility in common organic solvents and good self-film-forming properties. The semiconducting properties of the molecule, 2 were evaluated in organic thin film transistors (OTFTs). The molecule, 2 exhibits charge carrier mobilities-as high as 5.3 × 10-3 cm2 V-1 -1 (I ON/IOFF = 2.43 × 105) without thermal annealing process.
