We will investigate the role of structural, conformational details, as well as the dynamics and transport properties of the starting material (reactants) and products with immobilized catalysts within confined nanometer-sized geometries. From bottom-up we will study intermolecular interactions within the density-functional-theory approach. At larger scales we will quantify the transport of reactants and products in and out of confined spaces during the catalysis with a reactive or hybrid particle/lattice Boltzmann algorithm.
- Investigate the adsorption of self-assembled monolayers serving as linkers on gold substrates (with A2) and different oxides (with A5).
- Study the influence of linker type, length, head/tail groups etc. on the their stability on gold and oxide templates.
- Unravel the clicking of molecular probes and catalysts on the linkers using IR spectra as a basis.
- Calculate the properties, dynamics, and thickness of molecular linkers on mate rial substrates.
- Develop interaction parameters and force fields for linkers and catalysts in order to optimize follow-up more detailed modeling approaches.
- Investigating the impact different confinement effects on the selectivity of ring-closing diene metathesis reactions (B1) and finding the optimal location of a single catalyst.
- Develop an efficient numerical thermalized reaction-diffusion-transport model to investigate density distribution and flux field profiles for catalytic and transport pores under nano-confinement.
