Effect of substituents on the properties of distyrylarylene-based field-effect transistor materials
Two new distyrylarylene derivatives, 4,4′-bis(2-dibenzothienylvinyl)biphenyl (1) and 4,4′-bis(2-bithienylvinyl)biphenyl (2), were synthesized with good yields. Their properties are compared with 4,4′-bis[2-(3-N-butylcarbazolyl)vinyl]biphenyl (3). Our expe
