Disclosed are compounds according to formula (I), wherein R' and R'' are selected from the group consisting of R'=SiR1R2R3 and R''=H; R'=SiR1R2R3 and R''=SiR4R5R6; R'=Ar1SiR1R2R3 and R''=H; and R'=Ar1SiR1R2R3 and R''=Ar2SiR4R5R6; R1, R2, R3, R4, R5, and R6 are independently selected from the group consisting of hydrogen, alkyl, alkenyl, alkynyl, aryl, cycloalkyl, cycloalkenyl, cycloalkynyl, arylalkyl, arylalkenyl, and arylalkynyl; Ar1 and Ar2 are independently selected from the group consisting of arylene, arylenealkylene, arylenealkynylene, heteroarylene, heteroarylenealkylene, heteroarylenealkenylene and heteroarylenealkylene; and n is at least 20. Such compounds may be used as an emissive layer in a polymer light-emitting diode (PLED), which itself may be used in electroluminescent devices.
