Abstract
Schiff base 1，2-cyclohexyldiamino-N，N’-his(2-hydroxy一3.methoxvbenzaldehvde)(1)and its zinc complex(2) were synthesized.The structure of the ligand and its compound(2)was characterized bv IR and elemental analysis tech. niques.The UV-vis absorption and photoluminescence spectra of the compound(2)indicate that it iS a blue emitter under UV radiation while the effective energy.transfer from the ligand to the eentral Zn”ion occurs in the complex.The electro. chemical band gap is approximatively consistent with optical band gap estimated by UV-vis absorption spectral edge.The resuits indicated the complex(2)could emit intensive blue fluorescence with peak wavelength at 460nm and bandwidth of 72. 2nm under UV excitation at 365nm.The complex(2)of bright blue photoluminescence might be applied as luminescent in organic electroluminescence devices(oLEDs).-
