Fluorescent maleimides of Formula (I) wherein R1 and R2 independently from each other stand for (a), (b), (c), (d) or (e), (f) or (g) wherein Q1 stands for hydrogen, halogen, phenyl, -E-C1-C8alkyl, -E-phenyl, wherein phenyl can be substituted up to three times with C1-C8alkyl, halogen, C1-C8alkoxy, diphenylamino, -CH=CH-Q2, wherein Q2 stands for phenyl, pyridyl, or thiophenyl, which can be substituted up to three times with C1-C8alkyl, halogen, C1-C8alkoxy, -CN, wherein E stands for oxygen or sulfur, and wherei n R21 stands for C1-C8alkyl, phenyl, which can be substituted up to three time s with C1-C4alkyl, C1-C4alkoxy, or dimethylamino, and R22 and R23 independentl y from each other stand for hydrogen, R21, C1-C8alkoxy, or dimethylamino, or - NR4R5, wherein R4 and R5, independently from each other stand for hydrogen, phenyl, or C1-C8alkyl-carbonyl, or -NR4R5 stands for a five- or six-membered ring system, and R3 stands for allyl, (h), (i), (j), (k) or (l) wherein Q3 stands for hydrogen, halogen, C1-C8alkoxy or C1-C8alkyl-amido, unsubstituted or substituted C1-C8alkyl, unsubstituted or up to three times with halogen, - NH2, -OH, or C1-C8alkyl substituted phenyl, and Z stands for a di- or trivalent radical selected from the group consisting of substituted or unsubstituted cyclohexylene, preferably 1,4-cyclohexylene, triazin-2,4,6- triyl, C1-C6alkylene, 1,5-naphthylene, (m), (n), (o) wherein Z1, Z2 and Z3, independently from each other stand for cyclohexylene or up to three times with C1-C4alkyl substituted or unsubstituted phenylene, preferably unsubstituted or substituted 1,4-phenylene, and wherein R6 and R7, independently from each other stand for (p) n stands for 1, 2 or 3, and m stands for 1 or 2, with the proviso, that R1 and R2 not simultaneously stand for phenyl, and its different uses such as in electroluminescent devices and as void detection compounds.
