Blue organic light emitting materials from π-conjugated compounds

A series of π-conjugated compounds with bright blue photoluminescence property were designed and synthesized. The main structure comprises of fluorene as electron acceptor and thiophene as electron donor in order to increase the electron mobility. All the products were confirmed by proton, and carbon NMR, MS and elemental analysis as well. They might be widely applied as luminescent in organic light emitting diodes (OLED) which has been attracted much attention in recent years.
