The architecture of the red emitting organic dye plays a crucial role in light-emitting diodes. Efficient and stable deep red/near-infrared solid-state emitters are highly required to realize commercial devices as OLED or PLED. With the aim to optimize efficiency, one of the most widely investigated conjugated system is phenylenevinylene (PV) skeleton, with various substituents. The introduction of electron withdrawing groups on the vinylene moiety leads to a red shift of the emission maximum respect to less substituted phenylenevinylene systems. As a part of our continue research on highly emissive chromophores here we describe the synthesis and characterization of a new cyano-modified PV that acts as a red emitter dissolved in polar solvents, in its crystalline habitus and dispersed in a polymeric matrix.
