Abstract:
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.

Abstract:
PURPOSE: An electronic pen pressure measuring device is provided to supply a cheap electronic pen with reliability by including an elastic unit. CONSTITUTION: A moving plate comprises a capacitance sensor with first and second fixing plates(10a,10b) and is moved according to the change of pen pressure between the first and second fixing plates. A tip(40) is attached to the moving plate to generate the pen pressure. When the moving plate is moved in a first direction, an elastic unit(50) moves the moving plate to an original position. Spacers(30a,30b) are placed between the first and second fixing plates to smoothly move the moving plate. The elastic unit is not placed between the first and second fixing plates and is formed on the moving plate.
