Embodiment 1
[0027] A kind of synthetic method of triphenylene compound, described synthetic method comprises the following steps:
[0028] Raw material preparation:
[0029] 9-Fluorenone oxime, purity>97%, TCI (Shanghai) Chemical Industry Development Co., Ltd.;
[0030] 2-(Trimethylsilyl)phenyltrifluoromethanesulfonate, purity>95%, TCI (Shanghai) Chemical Industry Development Co., Ltd.
[0031] Specific synthesis process:
[0032] Under the condition of 66°C, 1.0mmol of 9-fluorenone oxime and 1.2mmol of 2-(trimethylsilyl)phenyltrifluoromethanesulfonate and 2.0mmol of cesium fluoride as base and 2mmol of 18-crown -6-ether was used as a phase transfer catalyst and reacted in 2 mL of anhydrous toluene solvent for 28 hours to obtain the crude product of the triphenylene compound; the crude product of the prepared triphenylene compound was washed with water, extracted with ethyl acetate, and spin-dried under reduced pressure, The volume ratio of ethyl acetate:petroleum ether=1:60 was separa...
