• Three di-substituted acetylenes in the tolane structure, 4-(trans-4-pentylcyclohexyl)-3',4'-difluorotolane (IM), 4-(trans4-heptylcyclohexyl)-4'-fluorotolane (2M), and 4-(4-pentylphenyl)-4'-fiuorotolane (3M), were polymerized in the presence of TaCl_5-based catalyst. The weight-average molecular weights Mw^^^→ of the polymers were high than 4 x l0^5. photoluminescence (PL) and electroluminescence (EL) of the three polymers made as single-layer device on indium-tin oxide glass (ITO), ITO/polymer/Al, have been comprehensively studied. By changing the structural conditions of polymer, such as introducing the fluorine atom or a long carbon chain to the end group of polymer side chains, the luminescence is clearly enhanced.
