Claim:
A compound as represented by the structure of formula (I): R(S 5 A 1 ) r (S 3 B 1 ) p S 1 -D-S 2 (B 2 S 4 ) q (A 2 S 6 ) t R p (I) wherein D is the divalent moiety: S 1 and S 2 are linking groups each independently selected from the group consisting of —O—, —OC(O)—, and —OC(O)O—; S 3 , S 4 , S 5 , and S 6 , are linking groups each independently selected from the group consisting of covalent bond, —O—, —S—, —C(O)—, —OC(O)—, —C(O)O—, —OC(O)O—, —OC(O)NR 1 —, —NR 1 C(O)O—, —SC(O)—, and —C(O)S—; R 1 is hydrogen or C 1 to C 4 alkyl; each B 1 and B 2 is a divalent radical independently selected from the group consisting of aliphatic and aromatic carbocyclic and heterocyclic groups having 1 to 16 carbon atoms; optionally having one or more fused rings and optionally mono- or polysubstituted with L; L is selected from the group consisting of the substituents F, Cl, —CN, and —NO 2 ; and alkyl, alkoxy, alkylcarbonyl, and alkoxycarbonyl groups, having 1 to 8 carbon atoms, wherein one or more of the carbon atoms are optionally substituted with F or Cl; A 1 is a divalent linear or branched alkyl having 2 to 20 carbon atoms, optionally interrupted by linking groups selected from the group —O—, —S—, —C(O)—, —OC(O)— and —C(O)O—; A 2 is a divalent linear or branched alkyl having 3 to 20 carbon atoms, optionally interrupted by linking groups selected from the group —O—, —S—, —C(O)—, —OC(O)— and —C(O)O—; R is selected from the group consisting of hydrogen, F, Cl, —CN, —NO 2 , and a monovalent linear or branched alkyl having 1 to 20 carbon atoms, optionally interrupted by linking groups selected from the group —O—, —S—, —C(O)—, —OC(O)— or —C(O)O—; R p is a polymerizable group; p and q are each independently an integer of 1 or 2; and r and t are each independently an integer of 0 or 1; provided that when R is hydrogen, F, Cl, —CN, or —NO 2 , and r is 1, S 5 is a covalent bond; and when R is hydrogen, F, Cl, —CN, or —NO 2 , and r is 0, S 3 is a covalent bond.
