Disclosed are compounds according to formula (I), n n n wherein R′ and R″ are selected from the group consisting of R′=SiR 1 R 2 R 3 and R″=H; R′=SiR 1 R 2 R 3 and R″=SiR 4 R 5 R 6 ; R′=Ar 1 SiR 1 R 2 R 3 and R″=H; and R′=Ar 1 SiR 1 R 2 R 3 and R″=Ar 2 SiR 4 R 5 R 6 ; n R 1 , R 2 , R 3 , R 4 , R 5 , and R 6 are independently selected from the group consisting of hydrogen, alkyl, alkenyl, alkynyl, aryl, cycloalkyl, cycloalkenyl, cycloalkynyl, arylalkyl, arylalkenyl, and arylalkynyl; n Ar 1 and Ar 2 are independently selected from the group consisting of arylene, arylenealkylene, arylenealkynylene, heteroarylene, heteroarylenealkylene, heteroarylenealkenylene and heteroarylenealkylene; and n n is at least 20. n Such compounds may be used as an emissive layer in a polymer light-emitting diode (PLED), which itself may be used in electroluminescent devices. |
