We are investigating the self-assembly of block copolymers in pores with diameters ranging from 20 nm to a few microns in order to fabricate nanorods and microrods with specific internal microphase structures (Fig. 1), as well as mesoporous nanorods and microrods (Fig. 2).

Figure 2. Transmission electron microscopy image of a mesoporous silica microrod obtained by using a block copolymer as a structure-directing agent.
