报告介绍 | 报告摘要:
The formation of chemical bonds depends strongly on the spatio-temporal conditions within an ensemble of starting molecules. We found that by using nanostructured surfaces on metallic single crystals, a significant increase of the reaction rate can be obtained, even with simple linear hydrocarbons exhibiting very poor chemical reactivity. By imposing appropriate self-organized nano-confinements on the metallic surface which promote heterogeneous catalysis, polymerization of the linear monomeric units at mild conditions is obtained via CH-activation. The concept can be extended to 2-dimensional Glaser-coupling reactions on low indexed surfaces. The examples presented demonstrate new pathways to generate specific chemical bond formation which is unlikely to occur with conventional chemical techniques. In the second part of the talk a novel approach for preparing a multimode near field optical probe the generation of biomimetic systems using Dip Pen Nanolithography (DPN) will be discussed. The latter allows us to write chemical diverse small structures for the interaction with biological systems such as biological cells. Recent developments and perspectives for the generation of biomimetic surfaces and sensor applications will be presented.
