In the design of LED polymers, which emit light in the blue to red region of the visible spectrum when used in LED devices, certain problems need to be addressed: quantum efficiency, thermal stability, the ability to form thin films without pinholes, and crystallinity. Currently, it is believed that incorporation of either an electron-injecting or a hole-injecting layer on top of the emissive layer improves the quantum efficiency. In this paper, we have developed the synthetic strategy to incorporate triphenylamine (possibly a hole-injecting functionality) into the backbone of a polymer at the same time allowing for the control o f color emission. Color emission can be altered by conjugation extension or by use of different di-Wittig salts.
