<p>An organic semiconducting compound comprises an optionally fused ring structure of formula (I)[Ar4- Ar2- Ar1- Ar3] (I)where Ar1, Ar2, Ar3and Ar4independently comprise monocyclic aromatic rings and at least one of Ar1, Ar2, Ar3and Ar4is substituted with at least one substituent X, which in each occurrence may be the same or different and is selected from the group consisting of (i) optionally substituted straight, branched or cyclic alkyl chains with 1 to 20 carbon atoms, alkoxy, amino, amido, silyl or alkenyl, or (ii) a polymerisable or reactive group selected from the group consisting of halogens, boronic acids, diboronic acids and esters of boronic acids and diboronic acids, alkylene groups and stannyl groups, and where Ar1, Ar2, Ar3and Ar4may each optionally be fused to one or more further rings. Examples include 5-7 fused rings including thiophene rings, with C12alkyl groups as side chains, and their use in organic field effect transistor devices.</p> |
