摘要：

A bicontinuous cubic structure was revealed by electron crystallography on a large-pore mesoporous silica with a cubic la3d symmetry synthesized by using a triblock copolymer as a structure-directing agent. Its reconstructed structure (picture, left) is composed of an enantiomeric pair of interwoven three-dimensional mesoporous networks. Ordered complementary pores form interconnections between the two main channel systems at a special flat point of the G-surface (right).
