Among the blue-, green-, and red -emitting materials required for full colour organic light emitting diodes (oleds), red emitting materials remain one of the great challenges in terms of both colour purity and efficiency for dynamic research.The most organic red emitters can be classified into two categories, polycyclic aromatic hydrocarbons (PAH) and electron donor- -bridge-electron acceptor (D- A) systems. Compared with PAH, D- A systems have remarkable advantage; the ease in the fine tuning of their photophysical and electrochemical properties. In this part we have synthesized dyes based on D- Bridge ÃÆâïÿÃœïÿÃÂœA system taking isophorone as a cyclic bridge.
