Patent ID: 7951796

Claim:
A compound according to formula (1): wherein: A is a six-link, unsaturated or saturated ring; Q 1 , Q 2 , Q 3 , Q 4 are each selected, independent of each other, from the group consisting of CH, C-halogen, C—O—(C 1 -C 10 )-alkyl, C—CF 3 , C—CN and CH 2 ; R 1 , R 2 , R 3 , R 4 , R 5 , R 6 , are each selected, independent of each other, from the group consisting of H, Halogen, C 1 -C 10 -alkyl, C 1 -C 10 -alkenyl, C 1 -C 10 -alkynyl, C 1 -C 10 -alkyloxy, CF 3 , NH 2 , and NHR 9 , whereby the radical R 9 , is selected from the group consisting of C 1 -C 10 -alkyl, C 1 -C 10 -acyl, NO 2 , and CN; X 1 and X 2 each are H, or X 1 and X 2 jointly form X, whereby: X is selected from the group consisting of CH 2 , CH 2 —CH 2 , CH═CH, O and S; Y 1 , Y 2 each, independent from each other, are unbranched or branched C 1 -C 10 -alkyl; Z is a structure element Z1 or Z2 as given below, whereby: Z1 has the following general formula (2): wherein: m is 1, 2, 3, 4, 5 or 6, R 7 , R 8 , are selected independently of each other from the group consisting of H, C 1 -C 10 -alkyl and C 1 -C 10 -acyl, or R 7 and R 8 are each CH 2 and can form a ring via a CH 2 —CH 2 bond; and Z2 has the following general formula (3): wherein: n is 2, 3, 4, 5 or 6.
