Example Embodiment
[0033] Example 1
[0034] The octaaminophenyl POSS (OAPS) is reacted with a quantitative p-toluenesulfonic acid in a molar ratio in a THF solution. The molar ratio of the amino group to the sulfonic acid group is 1 / 1 to generate cage octaaminophenyl silsesquioxane After separation, washing and drying of p-toluenesulfonate (OPAAS), the yield was 95.4%.
Example Embodiment
[0035] Example 2
[0036] The octaaminophenyl POSS (OAPS) is reacted with quantitative p-toluenesulfonic acid at molar ratio in THF solution, wherein the molar ratio of amine group to sulfonic acid group is 1 / 2 to form cage octaaminophenyl silsesquioxane After separation, washing and drying of p-toluenesulfonate (OPAAS), the yield was 95.7%.
Example Embodiment
[0037] Example 3
[0038] The octaaminophenyl POSS (OAPS) is reacted with a quantitative amount of methanesulfonic acid in a molar ratio in a THF solution, and the molar ratio of the amine group to the sulfonic acid group is 1 / 1 to form cage octaaminophenyl silsesquioxane Methanesulfonate (OAPS-MS) has a yield of 94.1% after separation, washing and drying.
