摘要：

A series of terminally protected alkyne derivatives iPr(3)Si-(Cequivalent toC)(n)-Si iPr(3), n=2, 3, 4, 6 was prepared by the Hay oxidative coupling. The longest oligoyne chain was in 1.12-bis-(triisopropylsilyl)-1,3,5,7,9,11-dodecahexayne (V), that is a new substance exhibiting reasonable stability even in the solid state (m.p. 112.5degreesC). The prepared oligoynes were studied by UV-Vis, Raman, FTIR, C-13-NMR and mass spectroscopy. The corresponding de-protected free alkynes polymerized spontaneously in n-hexane solution at room or sub-room temperatures towards new carbonaceous materials, which were characterized analytically and spectroscopically.
