Photo-crosslinked polymer cubosomes with surface functional groups as nanoreactors in organic solvents |
| 초록 |
Transient nanostructures formed by self-assembly of block copolymers can be covalently stabilized by cross-linking of block copolymers. Photodimerization of conjugated alkenes is an attractive method to cross-link polymers without using any additional reagents for cross-linking. We show the photo cross-linking of complex self-assembled nanostructures (polymer cubosomes) by [2π + 2π]-photocycloaddition of indene moieties present in polystyrene serving as a hydrophobic block of the block copolymer. The photodimerization resulted in the formation of complex three-dimensional porous structures that could maintain their structural integrity in organic solvents. Utilizing the large surface area of polymer cubosomes, organocatalysts such as proline could be introduced to the surface of the cross-linked mesoporous polymers, which could perform enantioselective aldol reactions in organic solvents. |
