(1),( 2) (, 3 ) and ( 4), wherein Z is a direct bond, O, S, CH2, SO, SO2, CO, RPO, CH2, alkenyl, alkynyl, a C1- C12 aliphatic radical, a C3-C12 cycloaliphatic radical, a C3-C12 aromatic radical or a combination thereof; R is a C6-I2 aromatic radical or a C1-12 aliphatic radical; R1 and R2 are independently H, halo, nitro, a C1-C12 aliphatic radical, a C3-C12 cycloaliphatic radical, a C3-C12aromatic radical, or a combination thereof; a is 0, 1, 2 or 3; b is 0, 1, 2, 3 or 4; m and n are independently 0 or 1; and Q and Z are different. |
