ABSTRACT:
A photosensing soluble organic semiconductor material is disclosed, which includes a Diels-Alder adduct which is a polycyclic aromatic compound with a dienophile. The polycyclic aromatic compound is pentacene. And the dienophile is represented by the formula of O═S═N—R1, wherein R1is SO2R2, SO3R2, SO2−, or SO3−; and wherein R2is selected from the group consisting of alkyl, alkoxy, acyl, aryl, aralkyl, chloroalkyl, fluoroalkyl, and substituted aryl with 1-12 carbon atoms. The structural formula of the adduct is as follows:
