AB - The invention relates to monomers, oligomers, and polymers I [R1, R2 = H, halo, (substituted) aryl, (substituted) heteroaryl, PSp, PSp, C≤20 alkyl (which may be (poly)substituted by F, Cl, Br, I, or CN and ≥1 nonadjacent CH2 groups may be replace by ≥1 of O, S, NH, NR0, SiR0R00, CO, CO2, OCO, OCO2, SCO, COS, CX2:CX2, or C≡C in such a manner that O and(or) S atoms are not linked directly to one another); R3, R4 = R1, Sn(R0)3, R(OR')(OR''), CH2Cl, CHO, CH:CH2, or SiR0R00,R000; R0, R00, R000 = H, C≤12 aryl, C≤12 alkyl; R', R'' = H, C1-12 alkyl, or OR' and OR'' together with the B atom form a C2-10 ring; X1, X2 = H, F, Cl, or CN; P = polymerizable group; P = group that can converted to or substituted by a polymerizable group P; Sp = a spacer group; n ≥ 1; wherein the recurring units can be identical or different and, in the case of n = 1 and R1 = R2 = H, then one or both of R3 and R4 = PSp, halo, Sn(R0)3, B(OR')(OR''), CH2Cl, CH:CH2, or SiR0R00R000]. These materials are useful as semiconductors or charge transport materials, in optical, electro-optical or electronic devices like LCD's, optical films, FET's or OFET's for TFT-LCD's and IC devices. A typical polymer was manufd. by bromination of 3-decylthienod[2,3-b]thiophene, and reaction of the resulting 2,5-dibromo-3-decylthieno[2,3-b]thiophene with MeMgBr, and polymn. of the resulting mono-Grignard product in the presence of (dppp)2NiCl2.
