Chromophore cpds. of formula (I) are new: A(B)x (I) A = the residue of a chromophore of the quinacridone, anthraquinone, perylene, indigo, quinophthalone, isoindolinone, isoindoline, dioxazine, phthalocyanine, diketopyrrolopyrrole or azo series with x N atoms bound to B, pref. with adjacent or conjugated carbonyl gp(s).; B = -C(=O)O-Q or 1, 2 or 3 B substits. may be H if x = 2, 3 or 4; Q = -CR1R2-CR3=CR4R5, -CR1R2-C IDENTICAL C-R6 or -CR1R2-C6H2R7(R8)2; R1, R2 = H; 1-24 C alkyl, opt. with O, S or N(R9)2 in the chain; 3-24 C alkenyl; 3-24 C alkynyl; 4-12 C cycloalkenyl or cycloalkyl; or phenyl or biphenyl opt. substd. by 1-6 C alkyl, 1-6 C alkoxy, halogen, CN or NO2; R3 - R5 = H, 1-24 C alkyl or 3-24 C alkenyl; R6 = H, 1-24 C alkyl, 3-24 C alkenyl, -C(O)-R10, -CO-C6H4-R11 or -C(=O)O-R12; R7, R8 = H, 1-6 C alkyl, 1-6 C alkoxy, halogen, CN, NO2, N(R9)2, or phenyl opt. substd. by halogen, CN, NO2, 1-6 C alkyl or 1-6 C alkoxy; R9, R10 = 1-6 C alkyl; R11 = H or 1- 6 C alkyl; and R12 = H, 1-6 C alkyl, or phenyl opt. substd. by 1-6 C alkyl. Also claimed are: (i) high mol. organic materials contg. (I) as fluorescent dye or bulk pigmented with the pigment A(H)x formed in in-situ thermal decomposition of a soluble cpd. (I); (ii) thermo-, photo- or chemosensitive materials and photo- and electroluminescent materials contg. (I); and (iii) a method for crystal modification conversion of chromophores A(H)x by converting to (I) and heating at 100-170 degrees C. |
