Abstract:
An electroluminescent device, comprising:an anode; a cathode; and an organic electroluminescent material including a dopant, and an organo-siloxane polymer, the main chain of said organo-siloxane polymer having an organic component selected from the group consisting of anthracene and pentacene, either individually or in combination, each of said anthracene and pentacene being either: substituted optionally with hydrogen, alkyl, aryl, heteroalkyl, heteroaralkyl, nitro, cyano, hydroxy, alkoxy, aryloxy, thio, alkylthio, arylthio, amino, halogen, dialkylamino, diarylamino, diaralkylamino, arylamino, alkylamino, arylalkylamino, carbonyloxy, carbonylalkoxy, carbonylalkyloxy, alkylcarbonyloxy, arylcarbonyloxy, alkoxylcarbonyloxy, sulfonyl, sulfonyloxy; alkyl bonded to an adjacent silicon atom of the organo-siloxane polymer; aryl bonded to an adjacent silicon atom of the organo-siloxane polymer; or, bonded to an adjacent silicon atom of said organo-siloxane polymer; said organic electroluminescent material being electroluminescently conductively coupled directly with said cathode and said anode such that said organic electroluminescent material emits light upon the application of a voltage across said cathode and said anode.
