SUMMARY:Functional Nanoscale and Hierarchical Materials by Crystallization
 -Driven Self-Assembly - Professor Ian Manners\, University of Bristol

DESCRIPTION:Molecular synthesis has evolved to a relatively advanced state
  allowing the creation of remarkably organic complex molecules of size < 1
  nm. However\, the ability to prepare well-defined materials in the 10 nm 
 – 10 micron size regime with controlled shape and size and structural hi
 erarchy is still in its relative infancy and currently remains the virtual
 ly exclusive domain of biology. In this talk recent developments concernin
 g a promising new route to well-defined 1D and 2D materials within this si
 ze regime\, termed “living crystallization-driven living self-assembly
 ” (CDSA)\, will be described. The “seeded growth” characteristic of 
 living CDSA means that the process can be regarded as a type of “living 
 supramolecular polymerization” that is analogous to living covalent (e.g
 . anionic) polymerizations of molecular monomers and also to biological 
 “nucleation-elongation” processes such as amyloid fiber growth. This a
 pproach uses block copolymers\, homopolymers with charged termini\, or pi-
 stacking molecules as building blocks and leads to uniform 1D and 2D nanos
 cale and hierarchical materials with a wide range of potential application
 s in areas such as electronics\, catalysis and biomedicine.\n
