Biography:

Petko St. Petkov is a full Professor of Theoretical Chemistry at the Faculty of Chemistry and Pharmacy, University of Sofia, Bulgaria. He received his Ph.D. in Computational Chemistry in 2009 and completed postdoctoral research at Jacobs University Bremen and Leipzig University, Germany. He was appointed Associate Professor in 2017 and currently serves as Vice-Dean, responsible for research, projects, and international relations.

His research focuses on density functional theory (DFT)-based modeling of metal clusters, metal oxides, and porous materials, with emphasis on their structural, spectroscopic, magnetic, and electronic properties. He is author/co-author of over 100 scientific publications. In 2024, he received the prestigious Pythagoras Award for Established Scientist in Natural and Engineering Sciences in Bulgaria.

Abstract:

Two-dimensional conjugated metal–organic frameworks (2D c-MOFs) are a novel class of layer-stacked MOFs with in-plane extended π-conjugation that exhibit unique properties such as intrinsic porosity, crystallinity, stability, and electrical conductivity as well as tailorable band gaps. Due to their unique features and high conductivity, 2D c-MOFs have displayed great potential for multiple high-performance energy, magnetic and (opto)electronic devices. In order to be able to ﬁne tune the properties of the 2D c-MOFs, a set of ligands in various combinations with functional groups (–NH2, –OH, –SH) and metal ions (Cu(II), Zn(II)) have been investigated. By means of DFT calculations, we aim to ﬁnd phase prediction between aromaticity descriptors and electronic properties of the investigated systems. Such approach was recently applied to 2D – covalent organic framework and up to some extend to 2D MOFs, showing prospect for further need of investigations.
