摘要：

The reaction of (c-C6H11)(8)Si8O12 1 with triflic acid (TfOH) can produce two different ditriflates with the formula (c-C6H11)(8)Si8O11(OTf)(2), which can be hydrolyzed selectively to four different incompletely condensed silsesquioxane frameworks with the formula (c-C6H11)(8)Si8O11(OH)(2) (2, 4, 7 and 8).
