ABSTRACT:
The invention relates to poly(tertiary di- or polyarylamines) which have more than one aryl moiety which is further substituted with a moiety capable of chain extension or crosslinking. In another aspect, the invention relates to poly(tertiary di- or polyarylamines) which have more than one aryl moiety which is further substituted with a moiety capable of chain extension or crosslinking which are partially or completely crosslinked or chain extended. The invention further relates to films prepared from such chain extended or crosslinked poly(tertiary di- or polyarylamines). The invention further relates to electrophotographic devices and electroluminescent devices, such as polymeric light-emitting diodes, containing such films.
