Solid-State Phase Transformation and Self-Assembly of Amorphous Nanoparticles into Higher-Order Mineral Structures

Room temperature self-assembly of mixed nanoparticles into photonic structures.

Manufacturing complex composites and structures using incompatible materials is central to next-generation technologies. In photonics, silica offers passivity, low loss and robustness, making it the ideal material platform for optical transport. However, these properties partly stem from the high-temperature processing conditions necessary for silica waveguide fabrication, restricting the funct...

Sumanenylferrocenes and their solid state self-assembly.

The first ferrocene-fused organometallic compounds derived from the buckybowl sumanene (C21H12) are presented. Both compounds, sumanenylferrocene and 1,1'-disumanenylferrocene, have been synthesized by Negishi-type cross-coupling of iodosumanene and were studied crystallographically. Sumanenylferrocenes form unique packing motifs, which are both different from those of their corannulene congene...

Higher-order organization by mesoscale self-assembly and transformation of hybrid nanostructures.

The organization of nanostructures across extended length scales is a key challenge in the design of integrated materials with advanced functions. Current approaches tend to be based on physical methods, such as patterning, rather than the spontaneous chemical assembly and transformation of building blocks across multiple length scales. It should be possible to develop a chemistry of organized ...
