| Abstract | A new kind of sandwich-like bis[2,3,9,10,16,17,23,24-octakis(octyloxy)phthalocyaninato] rare earth(III) complexes RE(Pc (*))(2) (Pc (*) = Pc(OC8H17)(8), RE=Er, Sm, Tb) are used as film-forming materials. Pure RE(Pc (*))(2) ultrathin films and RE(Pc (*))(2) and octadecanol (OA)/stearic acid (SA) mixed ultrathin films were prepared by the Langmuir-Blodgett (LB) technique. The LB films were characterized by ultraviolet/visible (UV/Vis) spectroscopy and X-ray photoelectron spectroscopy (XPS). The NO2 gas-sensing properties of SM(Pc (*))(2)/OA LB film are studied compared with that of (i-PrO)(4)CuPc LB film by XPS spectra and valence band spectra. It is found that the interaction between SM(Pc (*))(2) LB film and NO2-as is stronger than that between (i-PrO)(4)CuPe LB film and NO2 gas. Experimental results indicate that bis(phthalocyaninato) rare earth(III) complexes show more remarkable sensitivity than monophthalocyanine, which can be used in high-sensitive gas sensor applications. At the same time, the mechanism of sensitivity of SM(Pc (*))(2)/OA mixed LB film to NO, gas is also studied in this paper. (C) 2001 Elsevier Science B.V. All rights reserved. |
