CycloPUR – Fundamental insights in reversible polymerization of polyurethanes. University of Antwerp

Polyurethanes (PU) are versatile group of polymers, being used increasingly in diverse applications; for instance in mattresses, building foams, automotive and adhesives. PU is a cross-linked polycondensation polymer, in which polyols (polyhydroxyl alcohols) react with highly reactive diisocyanates. As a thermoset (they do not have a melting point), PU is difficult to recycle, and the current state-of-the-art mechanical recycling results in ...

Visible-light photoredox catalysis: synthesis of sulfonylated heterocycles via thiosulfonates. University of Antwerp

Pieter Mampuys
Organic synthesis (ORSY)
Visible light photocatalysis is an emerging technique in organic synthesis for the development of a wide range of previously inaccessible transformations. In this proposal the photoredox-catalyzed synthesis of sulfonylated heterocycles is described, making use of visible light and based on thiosulfonates (RSO2SR). The proposed method does not utilize (super)stoichiometric oxidants, required for the introduction of the sulfonyl group under ...

Development of polyoxometaltes as artificial enzymes for the selective hydrolysis of membrane- and glyco -proteins for proteomics applications KU Leuven

Tatjana Vogt
Sustainable Chemistry for Metals and Molecules

The total number of different proteins present in Earth organisms is estimated to be up to 10 million. While their identification in terms of primary sequences is expanding at an increasing rate, elucidation of their function and three-dimensional structure is drastically lacking behind. Most of the currently used approaches in proteomics for unraveling the structure and function of proteins require protein hydrolysis into more manageable ...

New avenues for small heterocycles: Expanding the horizon of intra-/inter-molecular trapping of in situ generated transient -alkyl-/vinyl-palladium(II) species. KU Leuven

Erik Van der Eycken
Sustainable Chemistry for Metals and Molecules

Transition metal catalysis lies at the heart of modern innovative science. To expand this area in organic synthesis, the challenge is to identify novel strategies for the formation of organo-metallic intermediates under mild conditions, and to discover new methods for their subsequent transformation. In this proposal we will focus on the trapping of transient C(sp3)- and C(sp2)-Pd species via C-H activation, or employing oxygen/nitrogen ...

Development of high-performance ultra-low bandgap copolymers for near-infrared photodetectors. Hasselt University

Wouter MAES
Materials Chemistry, Engineering Materials and Applications, Organic and Bio-polymer Chemistry
Due to their application in night and thermal vision systems, infrared image sensors are truly imaginative. To date, they are produced via the so-called hybrid technology, in which both the detector and the electronic readout are prepared separately and then interconnected at the pixel level. Obviously, this is a time-consuming process, resulting in low throughput and thus high cost, limiting widespread use (e.g. smartphones). A monolithic ...

New redox mediators and improved electrocatalytic materials for the functionalization of carbon-hydrogen bonds by electrosynthesis. University of Antwerp

Tom Breugelmans
Organic synthesis (ORSY), Applied Electrochemistry & Catalysis (ELCAT)
Functionalization of inert carbon-hydrogen (C-H) bonds is an important reaction in the chemical industry. The introduction of functional groups (e.g. oxygen, nitrogen, sulfur, … atom) in otherwise inert molecules is necessary to construct more complex molecules for the bulk and fine chemicals industry. However, an organic molecule contains multiple C-H bonds (the most common bond in organic molecules) and the selective functionalization of a ...

Nickel-catalyzed imidoylative cross-coupling reactions. University of Antwerp

Bert Maes
Organic synthesis (ORSY)
During the research stay at UAntwerpen, nickel-catalyzed imidolyative cross-coupling reactions starting from readily available alkane- and arenecarboximidamides (amidine) substrates will be developed. This will deliver new synthetic methods to prepare important functionalized heterocycles, e.g. 5-aminopyrimido[4,5-d]pyrimidine-2,4(1H,3H)-diones, 4-imino-4H-imidazol-5-amines and 1,3,5- triazin-2-amines. Besides base metal catalysis, the use of ...

ZEOlites for the conversion of CO2 to fuels and chemicals KU Leuven

Michiel Dusselier
Centre for Surface Chemistry and Catalysis

ZEOCO2 is a pioneering and structured effort to comprehensively study the introduction of well-positioned Zn, Cu and acidic catalytic active sites in zeolites to directly convert CO2 into fuels and chemicals in one step. This offers step economy due to the possibility of coupling the hydrogenation of CO2 with further C-C coupling within the same heterogeneous catalyst. The synthesis of cheap, stable and active zeolites with Zn sites ...

Sugar-based chemicals and Polymers through Innovative Chemocatalysis and engineered Yeast (SPICY) Hasselt University

Materials Chemistry, Organic and Bio-polymer Chemistry
SPICY's main aim is to provide chemical industry with new or optimized processes to convert sugars into added value compounds, i.e. both drop-ins and novel biobased chemicals. Two complementary lines are hereto developed in parallel, one focusing on biotechnology based on improved yeast-strains and one based on chemocatalytic routes. Both will aspire to meet industrial standards of productivity, titer, yield and selectivity, to safeguard ...
