中文摘要：
以芴（1）为原料，浓硝酸／浓硫酸为硝化剂，合成了2，7-二硝基-9，9．二辛基芴，其结构经1HNMR和IR确证。最佳反应条件为：120mmol，n（1）：n（HN03）=1：18，C（H2SO。）=15．3mol·L-1，于10℃反应7h，收率56％。
英文摘要：
2,7-Dinitro-9,9-dioctylfluorene was synthesized from fluorene（ 1 ） using nitrate/sulfate as the nitrating agent. The structure was confirmed by 1H NMR and IR. The optimum reaction condi- tions at 10 ℃ for7 h were as follows： 1 was20 rnmol, n（1） ：n（HN03） was 1：18, c（H2S04） was 15.3 mol·L-1 , the yield was 56% under the optimum reaction conditions.
