Processes and Properties of Organic/Inorganic Interfaces and Hybrids

Adsorption and self-assembling of organic molecules at various interfaces is a unique strategy for constructing smart materials. Along with subatomic design of the components, the orientation of the molecules on the surface is a crucial parameter that affects, for example, the transformation of light into electricity (I). This snapshot illustrates thin film morphology of acceptor-substituted quarterthiophene on silica. Biomolecular adsorption layers on hydrophobic (graphite) or hydrophilic (mica) substrates can provide valuable information on their biochemical functions and serve as a platform for encapsulation of micro-sized objects (II, diantennary oligoglycines). (III) Carbon nano-sheets prepared from thiophene-peptide “molecular chimeras” is one example of surface functionalization.
