Self-Assembly of Anisotropic Nanostructures

[摘要] Controlling and manipulating the physical and chemical intrinsic properties of nanomaterials has been a fascinating issue in chemistry and materials science. Two central geometric variables, size and shape, strongly affect the intrinsic properties of nanomaterials. Specifically, the shape of nanocrystals plays a pivotal role in the determining intrinsic properties, including optical, electronic, magnetic, and catalytic behavior. Since nanocrystals with tailored geometries possess unique shape dependent behaviors, considerable efforts to develop shape controlled inorganic materials and to investigate their shape anisotropic effects on functional properties are currently being undertaken. This dissertation will introduce specific shape anisotropic behavior of the shape modified particles achieved through two different synthetic routes: i) structural modification of shape anisotropic particles and ii) 3-dimensional self-assembly via microwave-assisted solvothermal reactions. Each topic section will systematically provide an approach on enhancing each specific intrinsic property originating from self-assembly of anisotropic nanostructure and will discuss the fundamentals behind these phenomena.
