TECHNOLOGY FOCUS - ORGANIC CHEMISTRY - Preparation (disclosed): 2-(2-(2-hydroxy-ethoxy)-ethoxy)-ethanol is protected by tosyl group and reacted with 4-bromo-4'-hydroxy biphenyl, to form 2-(2-(2-(4'-bromo-biphenyl-4-yloxy)-ethoxy)-ethoxy)-ethanol. The resulting bromo biphenyl is acylated, to obtain acetic acid-2-(2-(2-(4'-bromo-biphenyl-4-yloxy)-ethoxy)-ethoxy)-ethyl ester. The obtained bromo biphenyl acetate is reacted with methoxy-containing compound of formula (1) in presence of benzene at 60 degrees C, to obtain acetylene derivative of formula (2). The obtained acetylene derivative is reacted with 2,5-diphenyl-3,4-di-p-tolyl-cyclopenta-2,4-dienone at 350 degrees C, to obtain hexa phenyl benzene derivative of formula (3). The acetoxy group of terminal of hexa phenyl benzene derivative is hydrolyzed, and coupled with 4,5,7-trinitro-9-fluorenone (TNF) carboxylic acid in presence of dicyclohexylcarbodiimide (DCC), to obtain TNF derivative of formula (4). The resulting TNF derivative is cyclized in presence of Lewis acid, to obtain hexa-peri-hexabenzocoronene derivative of formula (5).Preferred Compound: The hexa-peri-hexabenzocoronene derivative is a benzene-containing compound of formula (5). Preferred Definitions:    R1=10-30C alkyl group;    R5, R6=ethylene;    R2-R4=4,5,7-trinitro-9-fluorenone-2-carbonyl group;    at least one of R2 and R3=-C6H4-OCH2CH2-(OCH2CH2)n-OCO-TNF; and    X=organic group chosen from alkyl group, alkenyl group, alkynyl group, aryl group, aralkyl group, heterocyclic group, halogen atom, alkoxy group, aryloxy group, alkylthio group, arylthio group, cyano group, amide group, acyl group and substituted silyl group.    EXAMPLE - Triethylene glycol (in g) (20) was dissolved in tetrahydrofuran (THF) (50 ml) and stir-mixed with sodium hydroxide aqueous solution (10 ml) for 30 minutes. Then, p-toluene sulfonyl chloride (5.07) dissolved in THF (20 ml), was dripped in the resulting solution and reacted for 1 hour. The reaction mixture was then poured into ice water and extracted by dichloromethane. An organic layer was separated, and water-washed, dried and purified, to obtain hexa-peri-hexabenzocoronene derivative (6.67) with yield of 82.24%.
