was synthesized and characterized. Zn(salen) exhibits high thermal stability
excellent thin film forming ability. Its HOMO
LUMO and electrochemical band gap were estimated to be-5.87 eV
-3.41 eV
and 2.46 eV by cyclic voltammetry
respectively. Zn(salen) powder exhibits bright blue emitting
but Zn(salen) film exhibits yellow emitting under radiation of 365nm. The device ITO/CuPc/NPD/Zn(salen)/Al could emit yellow light. The EL peak was at about 552 nm with CIE coordinates of
x
=0.504
y
=0.316. The device has a turn-on voltage of about 7.5 V and a maximum brightness of about 301 cd/m
