We explore innovative 2D materials

Theoretical Chemistry

The advances in nanotechnology have pushed materials science to the point where structural control at atomic precision is becoming feasible. This appears to mark the ultimate reachable limit for the atomistic design of materials with predestined properties. Twisting van der Waals homo- and heterolayers of 2D crystals against each other results in moiré structures and alternation of electronic properties of these materials. This is commonly referred to as twistronics. Existence of relation between the twist angle and the electronic properties has been predicted theoretically and experimentally.

In the Theoretical Chemistry group, we explore innovative materials, with a particular emphasis on two-dimensional systems, for use in energy storage and generation, catalysis, isotope separation, and nano(opto)electronic devices. To achieve this, we utilize a range of quantum-mechanical techniques to analyze the structural, electronic, vibronic, and optical characteristics of materials.

Molybdenum disulfide (MoS2) is a high-potential material for nanoelectronic applications, especially when thinned to a few layers. Liquid-phase exfoliation enables large-scale fabrication of thin films comprising single- and few-layer flakes of MoS2 or other transition-metal dichalcogenides (TMDCs), exhibiting variations…

Two-dimensional organic materials are mainly constructed by using orthogonal anisotropic connectivity of covalent bonding and π–π stacking. The noncovalent connectivity between building blocks is presumed to be too delicate to stabilize the two-dimensional (2D) layers. Contrary to this assumption, we constructed…

Electrically conductive coordination polymers (ECCPs), particularly those incorporating benzenehexathiol (BHT) ligands, are emerging as a distinctive class of electronic materials with tunable semiconducting and metallic properties. However, the exploration of novel ECCPs with low-symmetry structures and electrical…

With advanced synthetic techniques, a wide variety of well-defined graphene nanoribbons (GNRs) can be produced with atomic precision. Hence, finding the relation between their structures and properties becomes important for the rational design of GNRs. In this work, we explore the complete chemical space of gulf-edged…

The catalytic potential of flexible metal–organic frameworks (MOFs) remains underexplored, particularly in liquid-phase reactions. This study employs MIL-53(Cr), a prototypical “breathing” MOF capable of structural adaptation via pore size modulation, as a photocatalyst for the dehalogenation of aryl halides…

The advances in nanotechnology have pushed materials science to the point where structural control at atomic precision is becoming feasible. This appears to mark the ultimate reachable limit for the atomistic design of materials with predestined properties, which are defined by chemical composition and bonding…

Hydrogen is a crucial source of green energy and is extensively studied for its potential usage in fuel cells. The advent of 2D crystals (2DCs) has taken hydrogen research to new heights, enabling it to tunnel through layers of 2DCs or be transported within voids between the layers, as demonstrated in recent experiments…

PtSe2 is a promising 2D material for nanoelectromechanical sensing and photodetection in the infrared regime. One of its most compelling features is the facile synthesis at temperatures below 500 °C, which is compatible with current back-end-of-line semiconductor processing…

Due to the drastic required thermodynamical requirements, a photoelectrode material that can function as both a photocathode and a photoanode remains elusive. In this work, we demonstrate for the first time that, under simulated solar light and without co-catalysts, donor-acceptor conjugated acetylenic polymers (CAPs)…
