报告摘要

Precision chemistry is the basis for emerging materials with unprecedented physical phenomena. Precision materials combine local atomic precision with long-range order. Precision synthesis can link well-defined molecular building blocks to form long-range crystalline structures. This approach offers to combine the plethora of molecular functionality with the intrinsic properties of all mathematically possible lattices. Specially designed precision materials offer a variety of physical and chemical properties, such as topological features of the band structure (Dirac points, topologically flat bands, topological insulators), rich exciton physics, tunable electronic and optoelectronic properties, magnetic order, and highly selective catalytic and photocatalytic properties.

I will illustrate the raise of precision materials on a range of examples. They will include carbon nanoribbons, where there the edge decoration determines if they are topologically trivial or not [1]. In twisted transition metal dichalcogenide bilayers we show the emergence of superlattices that determine the band structure near the fermi level [2]. In the emerging class of two-dimensional organic crystals [3] we demonstrate metallic behaviour, [4] highly tunable photocatalytic properties [5] and metal-free magnetism [6]. Finally, I will show how the activity of isolated Cu(I) sites in metal-organic frameworks can be boosted to become selective for the separation of helium isotopes [7].

Thomas Heine, FRSC, MAE (PhD 1999, venia legendi 2006 TU Dresden) started his research group in 2008 at Jacobs University Bremen, moved in 2015 to University of Leipzig and 2018 to his current position as chair professor of theoretical chemistry at TU Dresden. He is a Clarivate Highly Cited Researcher with more than 430 peer-reviewed articles, an h-index of 102 (ISI) / 113 (Google Scholar), and more than 48000 citations. Prof. Heine is elected member of the Review Board of Deutsche Forschungsgemeinschaft (DFG). He coordinates DFG Collaborative Research Center 1415 “Chemistry of Synthetic 2D Materials, Priority Program PP 2244 “2D Materials: Physics of van der Waals [hetero]structures”, the DFG Researcher Training Group RTG 2861 “Planar Carbon Lattices”. He holds a prestigious ERC Synergy Grant (2DPolyMembrane) and a DFG Reinhart-Koselleck project (top funding scheme for individuals by DFG). His current research interests focus on magnetic metal-free materials and of precision membranes for selective unidirectional ion transport.
