Patent ID: 8242223

Claim:
An electronic device comprising a photoactive layer comprising at least one photoactive material and at least one polymer host, wherein the polymer host is made from at least one monomer having Formula I, or made from at least one monomer having Formula I and at least one comonomer selected from the group consisting of Formulae II, III, IV, V, VI, VII and VIII: where Formula I is: where: R and Y are independently selected from the group consisting of H, D, alkyl, fluoroalkyl, aryl, fluoroaryl, alkoxy, aryloxy, NR″2, R′, R′ is a crosslinkable group; R″ is independently selected from the group consisting of H, alkyl, fluoroalkyl, aryl, fluoroaryl, and R′; X the same or different at each occurrence and is a leaving group; Z is C, N, or Si; Q is (ZR″ n ) b ; a is an integer from 0 to 5; b is an integer from 0 to 20; c is an integer from 0 to 4; q is an integer from 0 to 7; and n is an integer from 1 to 2; where Formulae II through VIII are: where: R and Y are independently selected from the group consisting of H, D, alkyl, fluoroalkyl, aryl, fluoroaryl, alkoxy, aryloxy, NR″ 2 , R′, R′ is a crosslinkable group; R″ is independently selected from the group consisting of H, alkyl, fluoroalkyl, aryl, fluoroaryl, and R′; Q is (ZR″ n ) b ; X can be the same or different at each occurrence and is a leaving group; Z is C, N, or Si; E is (ZR″ n ) b , O, S, Se, or Te; a is an integer from 0 to 5; b is an integer from 0 to 20; c is an integer from 0 to 4; q is an integer from 0 to 7; and n is an integer from 1 to 2; with the proviso that the copolymer is made by Yamamoto polymerization.
