Abstract:
1. A process comprising: (a) coupling at least one quaterrylene compound of the formula (II) with at least one compound of the formula (III) where Y and Y each R and R aryloxy, arylthio, hetaryloxy or hetarylthio, to each of which may be fused further saturated or unsaturated 5- to 7-membered rings whose carbon skeleton may be interrupted by one or more —O—, —S—, —NR (i) C (ii) C (iii) aryl or hetaryl to which may be fused further saturated or unsaturated 5- to 7-membered rings whose carbon skeleton may be interrupted by one or more —O—, —S—, —N═CR (iv) a —U-aryl radical which may be mono- or polysubstituted by the above radicals specified as substituents for the aryl radicals (iii), where U is a —O—, —S—, NR (v) C each R′ is independently hydrogen; C C aryl or hetaryl to which may be fused further saturated or unsaturated 5- to 7-membered rings whose carbon skeleton may be interrupted by one or more —O—, —S—, —NR each R″ is independently hydrogen, C R R C aryl or hetaryl to each of which may be fused further saturated or unsaturated 5- to 7-membered rings whose carbon skeleton may be interrupted by one or more —O—, —S—, —CO— and/or —SO and where m, m1, n and n1 fulfill at least one of the following conditions: m=2, m1=1 and n and n1 are integers whose sum adds up to from 0 to 12; m=2, m1=2 and n and n1 are integers whose sum adds up to from 0 to 16; and (b) cyclodehydrogenating the reaction product obtained in (a) to give a rylene compound of the general formula (I)
