Patent ID: 8232550

Claim:
A composition comprising: a) a solvent mixture comprising i) an alkane having 6 to 16 carbon atoms present in an amount in a range of 1 to 20 weight percent based on a weight of the solvent mixture; and ii) an aromatic compound of Formula (I) present in an amount in a range of 80 to 99 weight percent based on the weight of the solvent mixture, wherein R a is an alkyl, heteroalkyl, alkoxy, heteroalkoxy, or a fused 5 to 6 member ring; each R b is independently selected from an alkyl, alkoxy, or a halo; n is an integer in the range of 0 to 5; and b) an organic semiconductor material dissolved in the solvent mixture in an amount equal to at least 0.1 weight percent based on a total weight of the composition, the organic semiconductor being of Formula (II) wherein, each R c is independently selected from an unsubstituted or substituted alkyl, an unsubstituted or substituted heteroalkyl, an unsubstituted or substituted alkenyl, an unsubstituted or substituted aryl, an unsubstituted or substituted heteroaryl, a ferrocenyl, or a silyl group of formula —Si(R d ) 3 ; each R d is independently selected from hydrogen, an unsubstituted or substituted alkyl, an unsubstituted or substituted heteroalkyl, an unsubstituted or substituted alkenyl, an unsubstituted or substituted alkynyl, a substituted or unsubstituted aryl, an unsubstituted or substituted heteroaryl, or acetyl; each X is independently selected from hydrogen, halo, alkyl, alkoxy, aryl, heteroaryl, alkenyl, cyano, or heteroalkyl; wherein a substituted alkyl or substituted heteroalkyl is substituted with at least one aryl, heteroaryl, halo, cyano, hydroxyl, or carboxyl group; and wherein a substituted alkenyl or substituted alkynyl is substituted with at least one alkoxy, aryl, heteroaryl, halo, cyano, hydroxyl, or carboxyl group; and wherein a substituted aryl or substituted heteroaryl is substituted with at least one alkyl, alkoxy, heteroalkyl, alkoxy, halo, cyano, hydroxyl, —SeH, or carboxyl group.
