以含有共轭大π键的对叔丁基杯[8]芳烃(Cal8)和十八(烷)铵(ODA)与Keggin结构和Dawson结构钼磷杂多酸(HPA)做成膜材料, 用LB技术制备了2种新型无机-有机杂化LB膜. 用π-A曲线、UV-Vis吸收光谱、荧光光谱和原子力显微镜(AFM)对标题LB膜的成膜性质、结构及发光性质进行了表征. 结果表明在空气/水界面Cal8/ODA/HPA杂化可形成稳定的单层与多层膜. 标题杂化LB膜的崩溃压为39.0 mN/m, 其粒子具有纳米尺寸, 在激发波长为280 nm时, 可观察到322~387 nm处由Cal8分子π-π*跃迁引起的荧光发射峰及510 nm处 杂多阴离子的配体到金属的荷移跃迁(LMCT)三重发射谱带.

Two new inorganic-organic hybrid LB films of tert-butylcalix[8]arene (Cal8)/octadecylammo- nium (ODA)/molybdophosphoricheteropolyacids (HPMo12, HP2Mo18) were prepared and characterized by π-A isotherms, UV-Vis absorption spectra, atomic force microscope and fluorescence spectra. The experimental results indicate that title compounds can form stable monolayer and polylayer films on the air/water interface. The collapse pressure of the title LB films was 39.0 mN/m. The fluorescence spectra showed that the emission peak during 322~387 nm was due to the π-π* transition in the Cal8 and the emission peak at 510 nm might correspond to the ligand to metal charge transfer (LMCT) triplet emission of .
