Patent ID: 7879256

Claim:
A compound of Formula (I): wherein R 1 and R 2 are each independently selected from the group: H, F, Cl and CH 3 ; n1 and n2 are each independently integers 3 to 20; m and p are each independently integers 0, 1 or 2; A is a divalent radical selected from the group: wherein R 3 -R 10 are each independently selected from the group: H, C1-C8 straight or branched chain alkyl, C1-C8 straight or branched chain alkyloxy, F, Cl, phenyl, —C(O)CH 3 , CN, and CF 3 ; X 2 is a divalent radical selected from the group: —O—, —(CH 3 ) 2 C—, and —(CF 3 ) 2 C—; and each B 1 and B 2 is a divalent radical independently selected from the group: R 11 -substituted-1,4-phenyl, wherein R 11 is H, —CH 3 or —OCH 3 ; 2,6-naphthyl; and 4,4′-biphenyl; with the proviso that when m+p is equal to 3 or 4, at least two of B 1 and B 2 are R 11 -substituted-1,4-phenyl.
