摘　　要：Isophorone based red fluorescent compound 3 (dicyanomethylene) 5,5 dimethyl 1 [2 ( N ethyl 3 carbazyl)ethylene]~cyclo^he^xe^ne (DCDCC) was synthesized for use in organic light emitting diodes (OLEDs). DCDCC was characterized by narrow emission in photoluminescence with full width at half maximum of only 50 nm in solution and in thin solid film of 70 nm width. Electroluminescence devices with configuration of ITO/NPB/Alq 3:DCDCC/Alq 3/Mg:Ag were fabricated utilizing DCDCC as dopant emitter. An efficient red emission peaked at 612 nm was obtained for the device with 1% (wt.%) DCDCC in Alq 3. The maximum luminance and current efficiency were as high as 3700 cd/m 2 at 14 V and 1.25 cd/A at 150 mA/cm 2, respectively.Isophorone based red fluorescent compound 3 (dicyanomethylene) 5,5 dimethyl 1 [2 ( N ethyl 3 carbazyl)ethylene]~cyclo^he^xe^ne (DCDCC) was synthesized for use in organic light emitting diodes (OLEDs).
