Synthesis and applications of soluble pentacene precursors and related compounds

The present disclosure relates to methods and systems for synthesis of bridged-hydropentacene, hydroanthracene and hydrotetracene from the precursor compounds pentacene derivatives, tetracene derivatives, and anthracene derivatives. The invention further relates to are methods and systems for forming thin films for use in electrically conductive assemblies, such as semiconductors or photovoltaic devices.

A dye compound is described, which is expressed by formula (I): wherein A, Aand Aeach independently represent a substituted or unsubstituted 1,4-phenylene or 2,5-thiophene group, and Band Beach independently represent a substituted or unsubstituted aryl group. The dye compound is suitably used as a dye sensitizer in a dye sensitized solar cell (DSSC).

Dye compound and dye-sensitized solar cell

A novel soluble pentacene (CH) precursor 6,13-dihydro-6,13-methanopentacene-15-one, a method for its production and intermediates therefor as well as pentacene films and coated surfaces. Thermolysis of the precursor at 150&#xb0; C. to 350&#xb0; C. induces an expulsion of carbon monoxide to generate pentacene in high yield. The high solubility of the precursor compound, as well as its production of non-contaminated pentacene, makes it an excellent material in the application of organic thin film transistors on surfaces.
