Porous organic cages.

Porous materials are important in a wide range of applications including molecular separations and catalysis. We demonstrate that covalently bonded organic cages can assemble into crystalline microporous materials. The porosity is prefabricated and intrinsic to the molecular cage structure, as opposed to being formed by non-covalent self-assembly of non-porous sub-units.

Dendron-grafted sulfur-terminated phenyleneethynylene molecular rods and blue luminescence self-assembly with Au nanoparticles.

Dendron-grafted phenyleneethynylenes with alpha,omega-disulfur containing groups were newly synthesized and characterized for self-assembly with Au nanoparticles; an intense blue photoluminescence of the composite film was observed.
