以刚棒状金乙炔咔唑基配合物(OMA)作有机组分,Keggin结构多金属氧酸盐钼磷酸H3PMo12O40作无机组分,用LB技术制备新型有机-无机纳米杂化LB膜.用-πA曲线、UV-Vis吸收光谱、荧光光谱(FS)、原子力显微镜(AFM)、扫描隧道显微镜(STM)进行表征,结果表明:标题LB膜具有交替排列的纳米层状结构,OMA/H3PMo12O40单层膜呈现半导体特性,当监控电压在-3- +3 V时,其隧道电流I值为±100 nA.
A new organometallic/inorganic nanohybrid LB film consisting of rigid-rod gold alkynyl complex(OMA) as the organic composite,Keggin type polyoxomexalate H3PMo12O40 as the inorganic composite,was prepared and characterized by π-A isotherms,UV-vis absorption spectra,fluorescence spectra(FS),atomic force microscopy(AFM),scanning tunneling microscopy(STM) and surface photovoltage spectroscopy(SPS).The experimental results indicated that the title LB film showed the lamellar structure:the monolayer of H3PMo12O40 alternating with bilayers of the organometallic com-pound,and that OMA/H3PMo12O40monolayer film showed electronic conductivity of semiconductor,and the tunneling current amounted to ±100 nA when the voltage was set at ±3 V.
