| 摘要 |
The present invention relates to process comprising reacting a polyfluorenes comprising at least one structural group of formula I with an iridium (III) compound of formula II wherein, R1 and R2 are independently alkyl, substituted alkyl, aryl, substituted aryl or a combination thereof; R5 is H or CHO; R3 and R4 are independently hydrogen, alkyl, substituted alkyl, aryl, substituted aryl or a combination thereof; R11 and R12 taken together form a substituted or unsubstituted monocyclic or bicyclic heteroaromatic ring; R13 is independently at each occurrence halo, nitro, hydroxy, amino, alkyl, aryl, arylalkyl, alkoxy, substituted alkoxy, substituted alkyl, substituted aryl, or substituted arylalkyl; Ar is aryl, heteroaryl, substituted aryl, substituted heteroaryl, or a combination thereof; X is selected from a direct bond, alky, substituted alkyl, and combinations thereof; Y is CHO or NH2; Z is CHO or NH2 where Z does not equal Y; and p is O, 1 or 2. The invention also relates to the polyfluorenes, which are products of the reaction, and the use of the polyfluorenes in optoelectronic devices. |
