查询词典 acridinium

These chemical shifts in the aromatic region of the resulting nucleophilic adduct 2-F were consistent with the counterparts of 9,10-dihydro-9-methoxy-9-(4-methoxyphenyl)-10-methylacridine, 17b which was proven to be the adduct of the 9-phenyl acridinium salt formed with an excess of MeOH (Figure S7 in Supporting Information).

Mol/L. 3 A study on the ECL of acridinum esters including 10--acridinium-9-carboxyl-phenyl-ester iodinate and 10-methyl-9-(p-formylphenyl)-acrdiniumfluorosulphonate in neutral solution was carried out. It was found both CACPEI and MFPA give strong ECL in KNO〓 solution when an appropriate voltage was applied on Pt electrode.

本文研究了碘化10-乙羧基吖啶-9-羧酸苯酯和对甲酰基苯基-10-甲基吖啶-9-羧酸酯氟磺酸盐的ECL行为，发现在中性KNO〓介质中，这两种吖啶酯都能在一定的电位下产生很强的ECL信号，考察了各种影响因素，确定了发光的最佳条件，探讨了可能的发光机理。

The products were identified by IR,NMR,MS and elemental analysis. In our method,K.OH was used in place of NaOH to synthesize benzyl ester of 3,5-dimethyl-4-hydroxybenzoic acid,2',6'-dimethyl-4'-(n-succinimidyloxycarbonyl) phenyl-acridinium-9-carboxylate was purified on a silica gel column with chloroform/ethylacetate(4:l,v/v) as eluent and further purified by triturating with hexane/acetone(2:l,v/v).The luminescence produced by DMAE-NHS is a flash light with maximumemission at 0.4s and decay half-time of 0.9s. The luminescence intensity is 6.11x10 cps/mol,which is affected by the composition of trigger and surfactant.

DMAE·NHS的合成是本论文的关键和难点，我们对文献方法进行改进：文献方法用氢氧化钠与3，5-二甲基-4-羟基苯甲酸反应制得3，5-甲基-4-羟基苯甲酸钠，再用3，5-二甲基-4-羟基苯甲酸钠与苄氯作用制备3，5-二甲基-4-羟基苯甲酸苄酯，我们用氢氧化钾代替氢氧化钠，使合成取得成功；在合成2'，6'-二甲基-4'-苯基-吖啶-9-甲酸酯时，文献方法对粗产品进行两次硅胶柱层析纯化，第一次柱层析用氯仿/乙酸乙酯(4：1，Ⅴ：Ⅴ)作溶剂和淋洗剂，第二次柱层析用己烷/丙酮(2：1，Ⅴ：Ⅴ)作溶剂和淋洗剂，按照文献方法得到的不是所需要的化合物，我们只进行第一次柱层析纯化，然后用己烷/丙酮(2：1，Ⅴ：Ⅴ)进行研磨，过滤，洗涤，除去溶于己烷/丙酮(2：1，Ⅴ：Ⅴ)的部分，得到所需要的产品。

With Death guitarist Schuldiner adopting vocal duties, the band made a major impact on the scene.

随着死亡的吉他手Schuldiner接受主唱的职务，乐队在现实中树立了重要的影响。

But he could still end up breakfasting on Swiss-government issue muesli because all six are accused of nicking around 45 million pounds they should have paid to FIFA.

不过他最后仍有可能沦为瑞士政府&议事餐桌&上的一道早餐，因为这所有六个人都被指控把本应支付给国际足联的大约4500万英镑骗了个精光。
