Electroluminescent devices and materials including an electroluminescent organo-siloxane polymer. The main chain of the organo-siloxane polymer comprises an organic component that can be alkenyl, alkynyl, aralkyl, aryl, heteroaralkyl, and heteroaryl which can be 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, or sulfonyloxy. The organic component includes at least two covalent bonds coupling the organic component to the main chain of the organo-siloxane polymer. Such devices provide superior performance and mechanical stability compared with conventional organic electroluminescent materials and devices made from such materials.
An electroluminescent device, comprising:
An organic electroluminescent material, comprising
An organo-siloxane polymer, comprising a main chain including silicon, oxygen, and an organic component selected from the group consisting of anthracene and pentacene being substituted optionally with hydrogen, alkyl, aryl, heteroalkyl, heteroaryl, nitro, cyano, hydroxy, alkoxy, aryloxy, thio, alkylthio, arylthio, amino, halogen, dialkylamino, diarylamino, diaralkylamino, arylamino, alkylamino, aralkylamino, carbonyloxy, carbonylalkoxy, carbonylalkyloxy, alkylcarbonyloxy, arylcarbonyloxy, alkoxylcarbonyloxy, sulfonyl, sulfonyloxy, wherein said organic component is coupled with a silicon atom in said main chain by at least one alkyl group having the formula —CH2(CH2)mCH2—, wherein m is an integer between 1 and 4 provided that said organic component includes at least two covalent bonds coupling said organic component with said main chain, and wherein said polymer is electroluminescent.
