Building a new structual oligo(phenylenevinylene) by linking trimeric phenylenvinylene (TPV) through the phenylâ phenyl bond of a central phenylene ring was reported. The resultant TPV dimers exhibit weak intermolecular interactions and intense blue photoluminescence in the solid state as well as high phase transition temperatures up to 250 °C. Organic light-emitting devices (OLEDs) based on these materials display blue emission with low turn-on voltage (about 3 V), maximum luminance approaching 2000 cd m<sup>â 2</sup> and efficiency up to 1.6 cd A<sup>â 1</sup>.
