Insoluble films of trisilanolisobutyl-POSS and octaisobutyl-POSS at the air/water interface are investigated by means of surface pressure - area per molecule isotherm (Pi - A) and Brewster angle microscopy (BAM). Analysis of the experimental results shows the partial cage molecule, trisilanolisobutyl-POSS, is a surface-active molecule that self-assembles into uniform monolayer upon compression; but the fully condensed cage molecule, octaisobutyl-POSS, is nonamphiphilic.
通过表面压力-每分子面积等温线（π-A）和布鲁斯特角显微镜（BAM）研究了三硅醇异丁基-POSS和八异丁基-POSS在空气/水界面的不溶性薄膜。实验结果分析表明，部分笼状分子三硅醇异丁基-POSS是一种表面活性分子，在压缩时会自组装成均匀的单分子层；但完全缩合的笼状分子八异丁基-POSS是非两亲性的。
