| Abstract: | We prepared triphenylamine (TPA)‐containing polymers by a direct oxidative‐coupling method, which showed high thermostability, good solubility, high quantum efficiency, and blue light emission. The polymers are characterized by Fourier transform infrared spectroscopy, 1H‐NMR, ultraviolet–visible spectroscopy, thermogravimetric analysis, elemental analysis, and fluorescence spectra. The homopolymeric TPA (PTPA) was fairly soluble in CCl4 and toluene, with a quantum yield of 0.38 relative to Rhodamine B in toluene solution, and showed blue light emission in solid‐state film. The TPA–stilbene copolymers were more soluble than the PTPA and showed violet to green light emission in solid‐state film, depending on the TPA moiety contents, from which a pure blue light emission could be obtained. The emitting quantum efficiency of the copolymers measured in toluene solution was from 0.57 to 0.78 relative to Rhodamine B. © 2002 Wiley Periodicals, Inc. J Appl Polym Sci 85: 2718–2724, 2002 |
