Amphiphilic ABC triblock terpolymer templated large-pore mesoporous silicas

• We design and synthesize the amphiphilic ABC triblock terpolymer template.
• We synthesize the large-pore mesoporous silica with two dimensional p6 mm structure and interconnected three dimensional porous structure.
• CSDA method is applied for preparing the large-pore mesoporous silicas.

The mesoporous silicas with two dimensional p6mm structure and interconnected three dimensional porous structure with large pore size of 16.9–18.0 nm were synthesized by the self-assembly of amphiphilic ABC triblock terpolymer, co-structure directing agent and silica source.
