Herein we report a "One-Pot" synthetic route for preparing 1,1,5,5-tetramethyl-3,3,7,7-tetraphenyl cyclo-tetrasiloxane and strictly alternating poly(dimethylsiloxane-alt-diphenylsiloxane) copolymers by heterofunctional poly-condenzation of diphenylsilanediol with dichlorodimethylsilane in the presence of two different amines, triethylamine and diethylamine, respectively. The products have been characterized by single-crystal X-ray diffraction, 1H, 13C and 29Si nuclear magnetic resonance spectroscopy, thermogravimetric analysis and differential scanning calorimeter. © 2013 Springer Science+Business Media Dordrecht.
