The controlled synthesis of multiarmed alternating thienylene–tetrafluorophenylene copolymers by the polymerization of 2-pentafluorophenyl-5-trimethylsilylthiophene under transition-metal-free conditions is demonstrated. The designed di- and trifunctional fluorosilicate initiators prepared by the reaction of 1,4- and 1,3-bis[(trimethylsilyl)ethynyl]benzene and 1,3,5-tris[(trimethylsilyl)ethynyl]benzene and tetrabutylammonium fluoride afford two-arm (I- and V-shaped) and three-arm (Y-shaped) polymers with controlled molecular weights and relatively low dispersities. The structures of the polymers were successfully confirmed using NMR spectroscopy.
