PENTACENE PRECURSORS, PENTACENE, METHOD FOR PREPARING THEM, ORGANIC THIN FILM TRANSISTOR USING THEM

摘要

Provided are pentacene precursors, which are synthesized by a Diels-Alder reaction, have high solubility in organic solvent, and produce pentacene via a retro Diels-Alder reaction by pyrolysis without using vacuum devices. The pentacene precursor is a Diels-Alder reaction product of an aromatic azine compound and a benzyne equivalent and comprises at least one -N=N- bridge on a 2 to 4-positioned benzene ring of the following formula(I). The aromatic azine compound is selected from phthalazine, pyridazine, or tetrazine. The benzyne equivalent is selected from tetrabromobenzene, 2,3-dibromonaphthalene, or phthalic anhydride.
