Functional Hybrids from Self-Assembly

Location: EB1 Room 1011

Friday, October 21st 2016 - 11:00 am

Global problems including energy conversion and storage, clean water and human health require increasingly complex, multi-component hybrid materials with unprecedented control over composition, structure, and order down to the nanoscale. This talk will give examples for the rational design of novel functional hybrid materials inspired by biological examples. These materials will include organic-inorganic hybrid nanoparticles as well as block copolymer directed polymer-inorganic hybrid materials. Discussion will include formation of hybrid nanoparticles and of synthetic porous materials with amorphous, polycrystalline, and epitaxially grown single-crystal structures. Experiments will be compared to theoretical predictions to provide physical insights into formation principles. The aim of the described work is to understand the underlying fundamental chemical, thermodynamic and kinetic formation principles enabling generalization of results over a wide class of materials systems. Examples will cover the formation of hierarchical structures at equilibrium as well as via processes far away from equilibrium. Targeted applications of the prepared systems will include the development of fluorescent hybrid probes for nanomedicine, nanostructured hybrids for energy conversion and storage devices, as well as the formation of first self-assembled superconductors.
