<p>The invention relates to quinones of formula (Ia) or (Ib), in which Formula (Ia) and Formula (Ib) R1 and R2 each independently represent - a hydrogen atom, - a C1-3O alkyl group in which one or more -CH2- linkages, apart from the attachment linkage, may be replaced by an oxygen atom, a sulphur atom, or an NH, N(C1-4 alkyl) or C=O group, and which is optionally substituted, or - an optionally substituted C6-10 aryl or C4-1O heteroaryl group, each R3 independently represents - a hydrogen atom, a linear or branched C1-3O alkyl group, in which one or more -CH2- linkages may be replaced by an oxygen atom, a sulphur atom, or an NH, N(C1-4 alkyl) or C=O group, and which is optionally substituted, or - a C6-1O aryl, C4-1O heteroaryl, (C6-10 aryl)carbonyl, or (C4-10 heteroaryl)carbonyl group, each of these groups optionally being substituted, and n is an integer between 1 and 5 inclusive. The invention also relates to a method for synthesizing these quinones and also to the use of these quinones as dyes, in particular dichroic dyes, and/or as charge carriers and/or exciton carriers in photoelectric devices.</p> |
