Prof. Heine is Full Professor of Theoretical Chemistry at TU Dresden and adjunct. Professor of Theoretical Physics at Jacobs University Bremen, Germany. In 1995 he received his diploma (physics) at TU Dresden. After postdoctoral stages at University of BolognaItalyand University of  GenevaSwitzerlandhe obtained his venia legend in Physical Chemistry at TU Dresden in 2006. In 2008 he started his research group as Associate professor at Jacobs University Bremen, where he was promoted to Full Professor in 2011. From 2015-2018 he held the Chair of Theoretical Chemistry at Leipzig University, and in 2018 he accepted the offer for the Chair of Theoretical Chemistry associated with a group leader position at the Helmholtz Center Dresden-Rossendorf. His research interest is the computational science of nanostructured materials, in particular of two-dimensional crystals and molecular frameworks. Prof. Heine is a highly cited author with more than 290 peer-reviewed articles, an h-index of 54(ISI) and he gave more than 50 talks at international workshops and conferences.


讲座摘要

The rich diversity of chemistry offers the possibility to create molecular framework materials with crystal structures that are mathematically and possible, but not present in nature. Such new crystalline materials may offer presently unknown states of matter that remain to be explored. Here, we concentrate first on 2D COFs which we have demonstrated can be synthesized in rich diversity The condition is a well-ordered crystalline network with nodes that interact electronically, which is only achieved if the chemical potential of the constituting building blocks are similar (as they are in COFs), and the coupling reactions result in a conjugated 2D network. We then show an example for a 2D kagome COF, which provides a very interesting electronic structure, namely a Dirac cone sandwiched by flat bands. By functionalization, these COFs can become single-band semiconductors, that is, they provide either only electrons or holes as mobile charge carriers.
