The author of the article were Hong, Wenjing; Li, Hui; Liu, Shi-Xia; Fu, Yongchun; Li, Jianfeng; Kaliginedi, Veerabhadrarao; Decurtins, Silvio; Wandlowski, Thomas. The article conveys some information:
A new and efficient approach using cleaving of trimethylsilyl groups to create covalent Au-C anchoring sites was developed for single-mol. junction conductance measurements. Employing the mech. controllable break junction (MCBJ) technique in liquid, the authors demonstrate the formation of highly conducting single mol. junctions of several OPE derivatives The created junctions are mech. stable and exhibit conductances around one order of magnitude higher than those of their dithiol analogs. Extended assembly and reaction times lead to oligomerization. Combined STM imaging and gap-mode Raman experiments provide structure evidence to support the formation of covalent Au-C contacts and further oligomerization. The experimental process involved the reaction of 1,4-Diethynyl-2,5-dimethoxybenzene(cas: 74029-40-6Electric Literature of C12H10O2)
1,4-Diethynyl-2,5-dimethoxybenzene(cas: 74029-40-6) belongs to ethers.Although ethers resist hydrolysis, they are cleaved by hydrobromic acid and hydroiodic acid. Hydrogen chloride cleaves ethers only slowly. Electric Literature of C12H10O2
