ABSTRACT:
The present invention relates to process comprising reacting a polyfluorenes comprising at least one structural group of formula Iwith an iridium (III) compound of formula IIwhereinR1and R2are independently alkyl, substituted alkyl, aryl, substituted aryl or a combination thereof;R5is H or CHO;R3and R4are independently hydrogen, alkyl, substituted alkyl, aryl, substituted aryl or a combination thereof;R11and R12taken together form a substituted or unsubstituted monocyclic or bicyclic heteroaromatic ring;R13is 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 NH2where Z does not equal Y; andp is 0, 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.
