Abstract
以含有共轭大π键的有机金属聚合物（OMP）作有机组分,以Keggin结构和Dawson结构钨（钼）磷杂多酸作无机组分,以十八胺为辅助成膜剂,用LB技术制备了3种新型有机金属聚合物/十八铵/杂多阴离子OMP/ODA/HPA（HPA=PMo12,PW12,P2Mo18）杂化LB膜.用π-A曲线﹑UV-vis吸收光谱﹑荧光光谱﹑原子力显微镜（AFM）﹑扫描隧道显微镜（STM）和表面光电压谱（SPS）对标题LB膜的成膜性能及光电性质进行了研究,结果表明标题杂化LB膜的崩溃压为26.8mN/m,在可见光区有较强的光电压响应,并有好的发光性质.当电压为±8.0V时,隧道电流是-0.1～-2.3nA.
