摘要 |
The present invention involves monomeric compounds having the structure: <IMAGE> Substituents W and Z are independently -CN, -NO2, -aryl, -aryl-V, -COX, SO2R, -H, or -alkyl. Substituent X is -OR, or -NR,R where R and R1 are independently -alkyl or -H. Substituent V is -halide, -NO2, -CN, -SO2R, or -COX. At least one of W and Z is -NO2, -SO2R, -CN, -COX or -aryl-V. In one preferred embodiment substituents W and Z are both -CN. In another preferred embodiment, substituent X is -NO2 or -CN and substituent Z is -C6H4NO2. These monomers are polymerized to form low bandgap polymers. |
