Abstract :
The design, synthesis and characterization of three novel fluorene-alt-thienylenevinylene-based copolymers have been reported. All these polymers consist of similar repeating unit, while thiophene unit with different substitution position is incorporated to well tune the conjugation degree that realizes multi-color luminance. These polymers show emission maxima in the blue, orange and red region of the visible spectrum. Considering the compatibility of luminescent materials with similar structure units, our methodology provides a facile and effective way for designing multi-color luminescent polymeric blending to realize full color electroluminescent (EL) devices. All these polymers have been successfully tested in single-layer sandwiched EL devices.
