摘要

Sub-nanomaterials are emerging materials developing recently. One-dimensional sub-nanomaterials (sub-nanowires, SNWs) possess unique polymer-like properties. So we used the polymer characterization and processing methods to study SNWs. For instance, GdOOH SNWs could be fabricated to high tensile strength fibers or large-area nonwoven mats by electrospinning; moreover, by wet-spinning, we could fabricate birefractive SNW films which emitted polarized fluorescent light when quantum dots added. In another work, without adding any chiral reagents, we prepared the macroscopic helical assemblies of SNWs through an evaporation-induced self-assembly process. Furthermore, we observed circular polarized luminescentlight from the helical assemblies with achiral organic fluorescent dye additives, because of chirality transfer from the helical assemblies to achiral organic molecules. Polyoxometalate clusters (POMs) can be regarded as zero-dimensional sub-nanomaterials. After adding rare earth elements and ligands, they self-assembled to SNWs. Furthermore, when we tuned the pH, the self-assembly behavior of POMs changed, resulting in nanorings and three-dimensional superstructures which performed enhanced activity in electrochemical sensing fields. These works revealed the huge potential of new functional SNWs in optic, mechanic and catalytic areas.
