TECHNOLOGY FOCUS - ORGANIC CHEMISTRY - Preparation (Disclosed): Amination reaction of halobenzofluorene derivative is carried out with secondary amine compound, and amine derivative is manufactured. Preferred Properties: The amine derivative has glass transition temperature of 120 degrees C or more and difference of lowest unoccupied molecular orbital and highest occupied molecular orbital of more than 3 eV. Preferred Definitions:    R1,R2=6-18C aryl or 5-18C heteroaryl (both optionally substituted);and    R3,R4=H, 1-6C linear, branched or cyclic alkyl, 1-6C linear, branched or cyclic alkoxy or R1.    SPECIFIC COMPOUNDS - 21 Amine derivatives e.g. 17,17-dimethyl-N,N-diphenyltetracyclo(8.7.0.02,7.011,16)heptadeca-1,3,5,7,9,11,13,15-octaen-14-amine of formula (A), 17,17-dimethyl-N-(naphthalen-1-yl)-N-phenyltetracyclo(8.7.0.02,7.011,16)heptadeca-1,3,5,7,9,11,13,15-octaen-14-amine, 17,17-dimethyl-N,N-bis(naphthalen-2-yl)tetracyclo(8.7.0.02,7.011,16)heptadeca-1,3,5,7,9,11,13,15-octaen-14-amine, 17,17-dimethyl-N-phenyl-N-(4-phenylphenyl)tetracyclo(8.7.0.02,7.011,16)heptadeca-1,3,5,7,9,11,13,15-octaen-14-amine and 17,17-dimethyl-N,N-bis(4-phenylphenyl)tetracyclo(8.7.0.02,7.011,16)heptadeca-1,3,5,7,9,11,13,15-octaen-14-amine are disclosed.    EXAMPLE - 1-(1-Hydroxy)ethyl-2-(4-chlorophenyl)naphthalene (in g) (2.8) and chloroform (20 ml) were added to a flask, and cooled. Boron trifluoride and diethyl etherate were added and stirred at room temperature for 1 hour. Water (20) was added, and reaction was completed. The organic layer was washed with water, concentrated and dried to produce 9-chloro-11-methyl-11H-benzo(a)fluorene (2.7). The obtained compound (2.7), benzyl triethyl ammonium chloride (2.3) and methyl iodide (4.3) were dissolved in dimethyl sulfoxide (20 ml). The solution was cooled, and sodium hydroxide aqueous solution (1.2) was added. Toluene (50 ml) was added, and organic layer was washed and dried to produce 9-chloro-11,11-dimethyl-11H-benzo(a)fluorene at yield of 72%.
