AbstractThe coordination of monolayer of amphiphilic ligands, N, N-bis(8-quinolinyl) alkyl propanediamide, H(2)A(alkyl = dodecyl, H(2)A(12); hexadecyl, H(2)A(16)) with Cu2+ at air-water interface was investigated by X-ray Photoelectron Spectroscopy (XPS) and UV-Vis spectra. The collapse pressure of the monolayers of H(2)A(12) and H(2)A(16) increased from 12.5 and 15.6 mN(.)m(-1) to 28.0 and 33.8 mN(.)m(-1) after their coordination with Cu2+ ions, respectively. XPS indicated that the coordination ratio between H(2)A and Cu2+ was 1:1. The binding energies of Cu2p were 935 and 955 eV. The Langmuir-Blodgett(LB) films of H(2)A(12) and H(2)A(16) can be used as transporting materials in three-layer electrolurruinescence devices: ITO/TPD/LB films/Alq(3)/Al. The driving voltages were 6.5 and 7.5 V, the maximum luminances were 621 and 201 cd(.)m(-2), respectively.
