Patent ID: 7282275

Claim:
A composition comprising: (a) a first compound of Formula I that is a charge transporting material, a charge blocking material, a light emitting material, a color conversion material, or a combination thereof, wherein Ar 1 is a first aromatic core and is a divalent, trivalent, or tetravalent radical of that is unsubstituted or substituted with one or more substituents selected from alkyl, alkenyl, alkoxy, aryl, aryloxy, fluoro, fluoroalkyl, perfluoroalkyl, diarylamino, cyano, nitro, ester, heteroalkyl, heteroaryl, and combinations thereof; EC is a first end capping group and is a monovalent radical of that is unsubstituted or substituted with one or more substituents selected from alky), alkenyl, alkoxy, aryl, aryloxy, fluoro, fluoroalkyl, perfluoroalkyl, diarylamino, cyano, nitro, ester, heteroalkyl, heteroaryl, and combinations thereof; n is an integer of 2 to 4, wherein the first end capping groups are identical; and each R is independently an alkyl, alkenyl, alkoxy, aryl, aryloxy, fluoro, fluoroalkyl, perfluoroalkyl, diarylamino, cyano, nitro, ester, heteroalkyl, heteroaryl, or combinations thereof; each R 1 is independently a hydrogen, alkyl, alkenyl, alkoxy, aryl, aryloxy, fluoro, fluoroalkyl, perfluoroalkyl, diarylamino, cyano, nitro, ester, heteroalkyl, heteroaryl, or combinations thereof; X is O, S, or NR 2 where R 2 is a C 1-30 alkyl, a C 1-30 heteroalkyl, a C 6-20 aryl, a C 3-20 heteroaryl, or a combination thereof; A is C, Si, Ge, Pb, or Sn; Z is NH or CH 2 ; t is an integer of 0 to4; and (b) a second compound that is selected from a charge transporting material, a charge blocking material, a light emitting material, a color conversion material, or a combination thereof, said second compound being a polymeric material having an aromatic radical that comprises the first aromatic core of the first compound, wherein the aromatic radical of the second compound can be unsubstituted, substituted with a substituent of a same type that is present on the first aromatic core of the first compound, or substituted with a substituent that is absent on the first aromatic core of the first compound, a second end capping group that comprises the first end capping group of the first compound, wherein the second end capping group can be unsubstituted, substituted with a substituent of a same type that is present on the first end capping group, or substituted with a substituent that is absent on the first end capping group; a divalent radical that comprises a divalent radical of the first end capping group of the first compound, wherein the divalent radical in the second compound can be unsubstituted, substituted with a substituent of a same type that is present on the first end capping group, or substituted with a substituent that is absent on the first end capping group; or a combination thereof, wherein the composition is amorphous and solution processible.
