Накратко на български

Двуизмерните материали, като молибден дисулфида, се модифицират чрез добавяне на метални комплекси за промяна на техните електронни и оптични свойства. Това помага за създаването на нови фотоелектронни устройства с подобрени технологични характеристики.

Tuning of 2D materials properties through controlled functionalization with opto-electroactive complexes

Two dimensional (2D) materials are a hot topic in chemistry, physics, materials science or even biology. However, proper functionalization of these ultrathin layers to tune their electronic charge and spin properties beyond current systems is still under development. In this scenario, Terpy2DMat pursued the tailoring of the electronic and optical properties of 2D transition metal dichalcogenides (TMDCs) through the anchoring of electroactive metal complexes. The specific goals of the project were: 1. Developing new protocols for functionalizing the exfoliated TMDCs surfaces with electroactive conjugated molecules 2. Full characterization of the hybrid structures by complementary techniques 3. Integration of the functionalized 2D materials into simple devices to prove their photo-electronic properties and potential technological applications To reach these goals we focused on the electrostatic functionalization of MoS2 layers (the most representative TMDC) with metallo-terpyridyl complexes.

Цел на проекта

Ultrathin two-dimensional nanosheets of layered transition metal dichalcogenides (TMDCs) are the fascinating materials for several applications in electronics, opto-electronics, spintronics, sensing, catalysis, energy storage and conversion, to name a few. The fields have witnessed huge attention world-wide in recent years. In spite of advancement of the 2D materials, there is a lack of proper chemical functionalization. Therefore, apposite functionalization of TMDCs to tune electronic charge and spin properties beyond current systems is extremely crucial. Herein, we propose chemical functionalization of 2D-TMDCs by optical and electroactive functional terpyridyl (tpy) complexes. The functional terpyridyl complexes offer numerous advantages including (i) much more robustness due to strong metal-to-ligand back bonding through [dπ(M)-pπ(L)] as compared to the organic ligands, (ii) versatile coordination modes, (iii) tunable, and reversible redox properties, and (iv) switchable metal-to-ligand charge-transfer (MLCT) band in the visible region. Through this functionalization we will be able to: I-Modify 2D materials properties at different level depending on: (i) The strength of the new interaction between complex and 2D crystal, from soft modification by electrostatic interaction to strong modification by covalent one; and (ii) the degree of functionalization, from low coverage of the 2D crystal to highly packed coverage giving rise to self-assembled monolayers (SAMs) formation.II-Tuning of the 2D crystals properties through the effect of light on the opto-electroactive complexes attached on them. The contribution from light-driven action to the electronic and magnetic properties will be deeply studied by the implementation of functionalized 2D-TMDCs into solid state devices, exploring their potential as logic gates and circuits or spintronic devices.
