首次报道了含有二乙炔的二烷基二硫键自组装单分子膜的形成。所用的二乙炔衍生物为[S(CH2)(2)COO(CH2)(9)C Drop CC Drop C(CH2)(13)CH3](2)，当从四氢呋喃中吸附到金上时，可以形成有序的单分子膜。通过短时间的紫外线照射，单体很容易转化为聚合物形式。形成了一种不受进一步照射的“蓝色”聚合物，也就是说，它没有变成“红色”。在聚合过程中，烷基侧链发生了一定程度的重组。
The formation of self-assembled dialkyl disulfide-functionalized monolayers containing diacetylenes is reported for the first time. The diacetylene derivative used was [S(CH2)(2)COO(CH2)(9)C drop CC drop C(CH2)(13)CH3](2) and was seen to form well-ordered monolayers when adsorbed on gold from THF. The monomer was readily converted to the polymeric form by a short exposure to UV radiation. A ''blue'' polymer was formed which was stable against further irradiation; that is, it did not become ''red''. During the polymerization the alkyl side chains displayed some reorganization.
