Chromophoric compounds and their preparation process

Chromophore, NLO-aktive Verbindungen der allgemeinen Formel 1 und Verfahren zur Herstellung solcher Verbindungen. Die erfindungsgemäßen Verbindungen können zur Herstellung von NLO-aktiven Polymeren und damit zum Aufbau von elektrooptischen und photonischen Bauelementen verwendet werden. New chromophore compounds are 7-aminophenoxazines (I) with a condensed carbo- or heterocyclic ring substituted by an electron acceptor-substituted methylene or imino group. New chromophore compounds are 7-aminophenoxazines, with a condensed carbo- or heterocyclic ring substituted by an electron acceptor-substituted methylene or imino group, of formula (I); R , R , R , R , R = hydrogen (I), linear or branched 1-20 carbon (C) alkyl (optionally with 1-5 ether oxygen (O) atoms in the chain), aryl or heteroaryl; R , R can also = benzyl; or one of R , R = is hydroxyl (OH) or carboxyl; Z = an electron acceptor-substituted methylene or imino group; X = sulfur (S), O, NR , a ring double bond or a (hetero)cyclic group of formula (II): ; T = CH or N; or optionally Z and T together = a structure of the type =N-SO2-C=, =N-CS-C= or =N-CO-C=; Y = CR or N; R , R = H, linear or branched 1-20 C alkyl, phenyl or naphthyl. An Independent claim is also included for the preparation of (I).
