Abstract
Dithienobenzodithiophenes of general formula (I) in which Rto Rare each independently selected from a) H, b) halogen, c) —CN, d) —NO, e) —OH, f) a Calkyl group, g) a Calkenyl group, h) a Calkynyl group, i) a Calkoxy group, j) a Calkylthio group, k) a Chaloalkyl group, I) a —Y—Ccycloalkyl group, m) a —Y—Caryl group, n) a —Y-3-12 membered cyclo-heteroalkyl group, or o) a —Y-5-14 membered heteroaryl group, wherein each of the Calkyl group, the Calkenyl group, the Calkynyl group, the Ccycloalkyl group, the Caryl group, the 3-12 membered cyc-loheteroalkyl group, and the 5-14 membered heteroaryl group is optionally substituted with 1-4 Rgroups, wherein Rand Rand Rand Rmay also together form an aliphatic cyclic moiety, Y is independently selected from divalent a Calkyl group, a divalent Chaloalkyl group, or a covalent bond; and m is independently selected from 0, 1, or 2. The invention also relates to the use of the dithienobenzodithiophenes according to any of claimstoas semiconductors or charge transport materials, as thin-film transistors (TFTs), or in semiconductor components for organic light-emitting diodes (OLEDs), for photovoltaic components or in sensors, as an electrode material in batteries, as optical waveguides or for electrophotography applications.
