摘要：

The structure of ethane-bridged PMOs was tailored for the first time through a post-synthesis method upon the addition of different sodium salts. It is proposed that the counterions can affect the surfactant micelles inside the PMOs, and further hydrothermal treatment will lead to a structure rearrangement of PMOs around the micelles. However, the results show that the effect of counterions on the structure of PMOs in the post-synthesis method is less pronounced compared with that of the effect in the direct-synthesis method, and additional surfactant is essential for maintaining the structure ordering of the materials.
