Then etc. 20.0g hydroquinones is dissolved in filling 50 DEG C of kieldahl flasks of hot water of 333mL, is cooled to slow at 20 DEG C It is slow that the dense H of 20mL are added dropwise2SO4, with the strict controlling reaction temperature of trash ice at 20~30 DEG C, then it is slowly added dropwise with constant pressure funnel 266.6mL K2Cr2O7Solution, contains K2Cr2O732.79g；Rear suction filtration is reacted and has obtained 1,4-benzoquinone crude product, drying has been washed with cold water Yellow 1,4-benzoquinone 9.5g is obtained, yield is 48.3%；
(2) synthesis of triphenol triacetate partially
In 100mL round-bottomed flasks, 40.0mL acetic anhydrides and the 2.0mL concentrated sulfuric acids are sequentially added, be stirred vigorously down and be dividedly in some parts 9.5g 1,4-benzoquinone, reaction temperature is between 40~50 DEG C in whole process；Continue stirring and be cooled to room temperature, be then poured into Sheng Have in the beaker of 150mL frozen water, there is substantial amounts of white precipitate to separate out immediately, stand suction filtration, ethyl alcohol recrystallization obtains white product 14.3g, yield 64.4%；
The synthesis and purifying of (3) 4,4 '-diformyl triphenylamine FTA
To 38.7mL DMF are added in 250mL round-bottomed flasks, at 0 DEG C, 23.3mL POCl are added dropwise over3, stirred in drop, mix Stirred 1 hour at 0 DEG C after even, then be stirred at room temperature 1 hour, be subsequently adding and be dissolved in 20mL CH2Cl2In 5g triphens Amine, is flowed back 48 hours at 80 DEG C of oil bath, and question response is cooled down after finishing, and normal temperature stands 15min and pours into frozen water, with 2mol/L's NaOH regulations are 7 to pH, use CH2Cl2Extraction removes a layer liquid, plus Na 3 times2SO4Dry, be then evaporated with Rotary Evaporators Yellow solid, uses CH2Cl2Dissolving, crude product obtains sterling through silica gel chromatograph post separation, and solvent is ethyl acetate:Petroleum ether=1: 10；
The synthesis of (4) 9,9 '-(N- phenyl-N, N-4,4 '-diphenyl) double fluorones
To the inclined triphenol triacetates of 3.4g and 60% ethanol 105mL is added in 250mL round-bottomed flasks, add with vigorous stirring Concentrated sulfuric acid 5.0mL, heating water bath dissolves it, and 1.2g 4 is added to it, and 4 '-diformyl triphenylamine, heating water bath dissolving is cold But 100 DEG C of oil bath flows back 48 hours after, stands cooling after completion of the reaction, suction filtration obtain dark green solid crude product 9,9 '-(N- phenyl- N, N-4,4 '-diphenyl) double fluorones；
Crude product 9,9 '-(N- phenyl-N, N-4,4 '-diphenyl) double fluorones, ethyl acetate are sequentially added in 250mL beakers 50mL, concentrated sulfuric acid 15mL, are stirred after shaking up, and suction strainer must be precipitated, washed with ethyl acetate for several times, and cumulative volume is 100mL, after suction filtration Precipitation is transferred in beaker, add water stirring, is heated one hour in water-bath, suction strainer goes out precipitation after cooling, washed with water dry Sterling 9,9 '-(N- phenyl-N, N-4,4 '-diphenyl) double fluorones.
4. according to claim 19,9 '-(N- phenyl-N, N-4,4 '-diphenyl) double fluorones, it is characterised in that：Should Compound is applied to Zn in the presence of surfactants2+The spectrophotometry of ion.
5. according to claim 19,9 '-(N- phenyl-N, N-4,4 '-diphenyl) double fluorones, it is characterised in that：Should Compound is applied to the Cu in fluorescence quenching method2+Detection.
