Abstract:
1. A method of preparing a substrate having thereon a patterned small molecule organic semiconductor layer, said method comprising: patternwise exposing a region of a substrate having thereon a film of a precursor of a small organic molecule to energy from an energy source to convert said film of a precursor of a small organic molecule to a patterned small molecule organic semiconductor layer to produce said substrate having thereon said patterned small molecule organic semiconductor layer; wherein said precursor is a Diels-Alder adduct of a polycyclic aromatic compound with a dienophile, wherein said polycyclic aromatic compound is selected from the group consisting of: oligothiophene, perylene, benzo[ghi]perylene, coronene and polyacene; and wherein said dienophile is represented by the formula: wherein X is N or CR wherein Y is selected from the group consisting of: N and CR wherein each R
