Patent ID: 8212243

Claim:
An organic semiconducting composition consisting essentially of an N,N-dicycloalkyl-substituted naphthalene diimide and a polymer additive comprising an insulating or semiconducting polymer having a permittivity at 1000 Hz of at least 1.5 and up to and including 5, wherein the organic semiconducting composition is capable of exhibiting a field electron mobility greater than 0.001 cm 2 /V·sec, the polymer additive has a permittivity at 1000 Hz of from 2 to 4, at least 95 weight % of its atoms are hydrogen, fluorine, and carbon atoms, and is a styrenic polymer, polyalkylene, poly(meth)acrylate, polyalkene, polynaphthalene, polycycloalkyl, or combinations thereof, and the polymer additive is present in an amount of at least 5 and up to and including 50 weight %, based on total organic conducting composition weight, and the naphthalene diimide is represented by any of the following Structures (IIIa), (IIIb), (IVa), and (IVb): wherein R 4 is a C 1 -C 12 alkyl group, C 2 -C 8 alkylene group, substituted phenyl or cyclohexyl group, C 1 -C 8 alkoxy group, C 1 -C 8 carbonyl, carboxy substituent, carbonyl-containing substituent, fluorine, or fluorine containing organic or inorganic group, R 8 is H, any of the substituents defined for R 4 , or an N,N′-cycloalkyl-substituted naphthalene-1,4,5,8-bis-carboximide moiety in which one of the imide nitrogen groups in the R 8 group is the point of attachment to the cyclohexyl group either directly or indirectly to provide a bis compounds based on a central moiety that is disubstituted with two N,N′-cycloalkyl-substituted naphthalene-1,4,5,8-bis-carboximide moieties, the Y groups are independently alkyl, alkenyl, alkoxy, aryl, or arylalkyl groups, halogens, cyano, fluorine-containing groups, carbonyl-containing or carboxy-containing groups, and m is an integer of from 0 to 2, and the naphthalene diimide is present in an amount of at least 50 and up to and including 95 weight %, based on the total organic semiconducting composition weight.
