Kim, Ji Ho published the artcileOxidative coupling polymerization of diethynylsilane derivatives and 1,2-diethynyl-1,1,2,2-tetramethyldisilane, Category: chlorides-buliding-blocks, the publication is Bulletin of the Korean Chemical Society (2006), 27(6), 869-874, database is CAplus.
The Glaser oxidative coupling polymerizations was performed on diethynyldiphenylsilane, diethynylmethylphenylsilane, diethynylmethyloctylsilane, and 1,2-diethynyl-1,1,2,2-tetramethyldisilane to afford polycarbosilanes containing diethynyl and organosilane groups in the main chain, such as poly(diethynyldiphenylsilane), poly(diethynylmethylphenylsilane), poly(diethynylmethyloctylsilane), and poly(1,2-diethynyl-1,1,2,2-tetramethyldisilane), resp. These obtained materials are almost insoluble in common organic solvents such as CHCl3 and THF probably due to the presence of a rigid rod diacetylene group along the polymer main chain. Therefore, the polymers were characterized using several spectroscopic methods in solid state. FTIR spectra of all the polymeric materials show that the characteristic CC stretching frequencies appear at 2147-2154 cm-1, in particular. The polymers in the solid state exhibit that the strong maximum excitation peaks appear at 260-283 nm and the strong maximum fluorescence emission bands at 367-412 nm, especially Thermogravimetric anal. of the materials shows that about 55-68% of the initial polymer weights remain at 400°C in nitrogen.
