The invention relates to multiple chromophores with a rylene base of general formula (I), where the variables have the following meanings: rylene is a group of formula (A), functionalised with at least one imide, ester, or amide group optionally additionally substituted with aryloxy, arylthio, heteroaryloxy and/or heteroarylthio, X is a rylene dicarboximide group absorbing at a wavelength different to the rylene group, bonded in the peri position to the rylene group by a group-Y'-A-Y-, bonded by the Y to the X group and optionally substituted by aryloxy, arylthio, heteroaryloxy and/or heteroarylthio, A is a bridging body comprising at least one aromatic or heteroaromatic group, groups Y or Y and Y' being bonded to the aromatic or heteroaromatic group, Y is a group (i),(ii), Y' is a group (i), (ii), (iii), (iv), groups (i) and (ii) may be part of the ester group of the rylene group, group (iii) may be part of the imide group of the rylene group and group (iv) may be part of the amide group of the rylene group, R1 = H or C1-C18 alkyl, where R1 groups may be the same or different when multiple groups are present, n = 1,2 or 3 and x = 1 to 7. |
