合成出三种新的四烷硫基取代的四硫富瓦烯衍生物，并用红外光谱、核磁共振谱、元素分析和质谱进行了表征，考察它们的成膜能力。结果表明这三种化合物的氯仿均可在亚相（水）上拉制出具有较好性质的ＬＢ膜，其成膜能力与烷基的碳链长度和亚相中甘酸的浓度有直接的关系。
Three new tetraalkylthio-substituted tetrathiafulvalene derivatives were synthesized and characterized by IR, 1HNMR, elemental analysis and mass spectrometry. The results showed that LB films with good properties could be drawn on the subphase (water) by the chloroform of these three compounds. The film forming ability was directly related to the carbon chain length of alkyl groups and the concentration of glycolic acid in the subphase .
