Patent ID: 7569728

Claim:
A compound having Formula (I): wherein: n is an integer greater than 1; R 1 is selected from aryl, heteroaryl, fluoroaryl, and fluoroheteroaryl; R 3 is selected from H and R 1 ; R 2 is selected from H, R 1 , alkyl, fluoroalkyl, Cl, Br, I and an arylamino group of Formula (II), wherein R 4 is selected from aryl, H, R 1 , alkyl, and fluoroalkyl; R 5 and R 6 are each independently selected from H, F, alkyl, aryl, alkoxy, aryloxy, fluoroalkyl, fluoroaryl, fluoroalkoxy, and fluoroaryloxy, and wherein R 5 and R 6 can, when taken together, form a ring; R 7 is selected from aryl, heteroaryl, fluoroaryl, and fluoroheteroaryl; and E is selected from O, S, (SiR 5 R 6 ) m wherein m is an integer of 1 to 20, (CR 5 R 6 ) m wherein m is an integer of 1 to 20, and combinations thereof, wherein R 5 and R 6 are each independently selected from H, F, alkyl, aryl, alkoxy, aryloxy, fluoroalkyl, fluoroaryl, fluoroalkoxy, and fluoroaryloxy and wherein R 5 and R 6 can, when taken together, form a non-aromatic ring, provided that when E is (CR 5 R 6 ) m , and n is greater than 1 and m is 1, at least one of R 5 and R 6 is not hydrogen or a hydrocarbon.
