Lee Group

This is the Nano-Science Center webpage of the Lee group, which is located at the Department of Chemistry (Organic Chemistry Section, Nanoscience Center) University of Copenhagen, Denmark. We are aiming to develop new catalytic methodologies for organic syntheses using state-of-the-art functionalized materials, contributing to society and scientific communities by providing solutions for current global issues.

Research

CO2-Upconversion

More than 13 gigatonnes of CO2 are released annually into the atmosphere as a result of fossil fuel combustion, causing climate changes and ocean acidification. In addition to carbon-capturing processes, CO2-functionalization using a catalytic process is an ideal solution towards creating more valuable resources to compensate the input energy
in the conversion process. This work implies that industrial waste, namely CO2 can be transformed to industrially useful chemicals, serving as a fuel source.

Asymmetric Catalysis and Origin of Life

Chirality on sp3-hybridized carbon is the fundemental resource for diversity and selectivity in Nature's many fascinating operations. We are highly focused on the developement of unprecedented asymmetric catalytic protocols. Furthermore, our methodology developement will be beneficial to understand the origin of chirality on Earth, which is one of the profound "unnatural" events on our planet. By taking advantage of knowledge in organo- and organometallic asymmetric catalysis, we will provide ground-breaking synthetic methodolgy for constructing from small to large and complex molecules in enantioselective fashion.

Novel Fluorination using Alkaline Metal Fluorides

Fluorine is the most electronegative element in the periodic table. This inherent atomic property renders various fascinating applications of fluorine atom in organic synthesis and material chemistry, particularly for the agrochemical and pharmaceutical industries. Moreover, the application of radio-active F[18] in PET imaging is of tremendous interest due to its huge impact in clinical oncology. Thermally-stable engineered solvents can promote the fluorination reaction using potassium fluoride with unprecedented selectivity towards SN2-products with high selectivity.

Catalytic Application of Functionalized Materials

Organic reations have been demonstrated under mostly homogeneous conditions. However, heterogeneous solid materials exhibit significant advantage, i.e. recyclability and high stability, therefore useful for many real-world applications. In our laboratory, we will tackle fundemantly important organic reactions using functinoalized state-of-the-art materials, for example, metal-organic frameworks (MOF), inorganic metal nanoparticles, functionalized polymers, in combination with high-performance organo- and organometallic catalysts.

Desalination

The increasing scarcity of potable water (drinking water) has been dramatically emphasizing the importance of seawater desalination as a primary means to obtain an ample and safe fresh water supply. Recent global climate changes are seemingly accelerating the unpredictability of
secure water supply sources—even in developed countries—threatening society’s sustainable growth. Seawater is a seemingly limitless water source, but obtaining energy-efficient desalination processes is a formidable challenge. Our group aims at facile desalination processes using functionalized organic materials, organic porous polymers, and membrane systems.
