New types of molecules, tetrasilylsilanes with the arms composed of oligothienylsilylvinyl units, were prepared by the platinum-catalyzed hydrosilation reactions. UV–Vis absorption and fluorescence properties of these molecules have been investigated. Polymer 9 showed good heat resistance against Td10 (10% weight loss temperature) at 402 °C even in air.
