Alternately, a tetrahydro diazapentacene tetrone derivative of formula (B1) is reacted with compound of formula: Rf3-Si(CH3)3 to obtain substituted diazapentacene derivative of formula (B11), which is deprotected to obtain diazapentacene diol derivative of formula (B12). The compound (B12) is aromatized and oxidized to obtain fluorine-containing aromatic compound of formula (IV). SPECIFIC COMPOUNDS - 1 Fluorine-containing aromatic compound is specifically claimed i.e. 6,13-bis(trifluoromethyl)-5,7,12,14-tetraazapentacene of formula (Ia).    EXAMPLE - 2.8 g 2,5-Dihydroxy-1,4-benzoquinone, 8.64 g o-Phenylenediamine and 50 ml acetic acid were stirred for 8 hours, and cooled to room temperature, filtered, and washed with acetone to obtain 5,7,12,14-tetraaza-5,14-dihydropentacene. 4.46g 5,7,12,14-Tetraaza-5,14-dihydropentacene, 200 ml water, 50 ml sulfuric acid, 17.65 g potassium dichromate were stirred at 120 degrees C for 1 hour to obtain 3.96 g 5,7,11,14-tetraaza-6,13-pentacenequinone. 0.562 g 5,7,11,14-Tetraaza-6,13-pentacenequinone, and 15 ml tetrahydrofuran were added to 0.109 g cesium fluoride, and the reaction solution was cooled at 0 degrees C. 0.8 ml Trifluoromethyltrimethylsilane was dripped slowly into reaction mixture, stirred at room temperature for 15 hours, and reacted was stopped using ammonium chloride saturated aqueous solution. 10 ml tetrahydrofuran was added to the obtained solid, and cooled to 0 degrees C, 3.7 ml tetra-n-butylammonium fluoride was dripped and stirred for 3 hours to obtain 0.4063 g 5,7,11,14-tetraaza-6,13-bis(trifluoromethyl)-pentacene-6,13-diol, which was used to obtain 5,7,12,14-tetraaza-6,13-bis(trifluoromethyl)-5,14-dihydropentacene. 0.191 g 5,7,12,14-Tetraaza-6,13-bis(trifluoromethyl)-5,14-dihydropentacene, 10 ml chloroform were subjected to freezing deaeration, 0.584 manganese dioxide was added and stirred for 5 hours. Manganese dioxide was removed by performing cerite filtration and the solution was concentrated to obtain 0.1644 g 6,13-bis(trifluoromethyl)-5,7,12,14-tetraazapentacene (87%).
