Patent ID: 7719000

Claim:
An organic semiconductor composition, comprising: a first quantity of a first aromatic ring compound according to Formula I; (Ar 1 ) a —(Ar 2 ) b —(Ar 3 ) c Formula I wherein Ar 1 , Ar 2 and Ar 3 are each independently selected from a group consisting of substituted and unsubstituted C6-C30 aryl groups or substituted and unsubstituted C2-C30 heteroaryl groups, at least one ring carbon of at least one of Ar 1 , Ar 2 and Ar 3 is substituted with nitrogen or oxygen, and a, b and c are each independently selected from integers from 0 to 20 and satisfy the expression (a+b+c) >0; and a second quantity of a second aromatic ring compound according to Formula II; (Ar 4 ) d —(Ar 5 ) e Formula II wherein Ar 4 and Ar 5 are each independently selected from a group consisting of substituted and unsubstituted C6-C30 aryl groups and substituted and unsubstituted C2-C30 heteroaryl groups, at least one hydrogen atoms thereof being substituted with a substituent containing —NH or —OH, d and e are each independently selected from integers from 0 to 10 and satisfy the expression (d+e)≠0, and the first aromatic ring compound according to Formula I and the second aromatic ring compound according to Formula II are joined by hydrogen bonds.
