Abstract
The invention relates to chromophoric NLO-active compounds of the general formula and to a process for preparing such compounds. The compounds according to the invention can be used for preparing NLO-active polymers and thus for constructing electrooptical and photonic components.
Claims14
A chromophoric compound of the general formula 1
- where
- R1, R4, R5 are each a hydrogen atom, a linear or branched C1- to C20-alkyl radical which is optionally interrupted by 1 to 5 ether oxygen atoms, or an aryl or heteroaryl radical;
- R2, R3, which can be the same or different, are each a hydrogen atom, a linear or branched C1- to C20-alkyl radical which is optionally interrupted by 1 to 5 ether oxygen atoms, a benzyl radical or an aryl or heteroaryl radical, where one of the radicals R2 and R3 optionally has a hydroxyl or carboxyl group;
- provided that R1 and R2 or R2 and R3 or R3 and R4 taken together jointly form a 5-membered or 6-membered ring;
- Z is a methylene or imino group bearing an electron-acceptor cyano and/or alkoxycarbonyl substituent;
- X denotes
- where T denotes CH or N;
- and
- Y is a CH or CR7 group or N where R7 is a linear or branched C1- to C20-alkyl radical or a phenyl or a naphthyl radical.
