Abstract

First generation thiophene-labeled conjugated dendrimers have been synthesized through the Heck coupling reaction between the 5-hexyl-5-propenyl thiophene derivative and 1, 2, 4, 5-tetrabromo-benzene as the core. They display a p -type semiconducting behavior and a considerably better solubility than the linear conjugated oligothiophene. Two crystalline dendrimers such as 4(HPBT)-benzene and 4(HPTT)-benzene showed carrier mobilities as high as 6.2× 10-3 and 2.4× 10-4 cm2 V-1 s-1, respectively.
