Low bandgap copolymers based on monofluorinated isoindigo towards efficient polymer solar cells Hasselt University
To explore the effectiveness of monofluorinated isoindigo as an electron-deficient building block in push-pull conjugated polymers for organic solar cell applications, four low bandgap copolymers are effectively synthesized and characterized. The effects of fluorine introduction, thiophene spacer length and polymer molar mass on the general electro-optical polymer characteristics, thin film blend microstructure and electronic performance are ...
Asymmetric incorporation of silver nanoparticles in polymeric assemblies by coassembly of tadpole-like nanoparticles and amphiphilic block copolymers Ghent University
Photoluminescent polymeric micelles from poly(ethylene oxide)- block -poly(((4-vinylphenyl)ethene-1,1,2-triyl)tribenzene) diblock copolymers University of Antwerp
In this contribution, we report the preparation of photoluminescent polymeric micelles via the self-assembly of amphiphilic diblock copolymers. First, poly(ethylene oxide)-block-poly(((4-vinylphenyl)ethene-1,1,2-triyl)tribenzene) (PEO-b-PTPEE), a novel diblock copolymer bearing an aggregation-induced emission (AIE) fluorophore subchain (viz. PTPEE) was synthesized via reversible addition–fragmentation chain transfer (RAFT) polymerization. The ...
POLY 293-Development of a novel biosensor platform based on a combination of molecularly imprinted polymers (MIPs) and conjugated polymers Hasselt University
Molecular imprinted polymers(MPIs) attract considerable interest as synthetic materials mimicking molecular recognition of natural receptors. However, integration of MIPs in clinical diagnostics is difficult because of limitations involving the integration of MIPs with transducers and the transformation of binding events into measurable signals. As a universal solution to these limitations a novel biosensor platform has been developed, in which ...
A Magnetic Field Fiber Optic Sensor with Magneto-optic Polymers and Nanoparticle Core-Shell Polymers KU Leuven
Shape recovery of thermoset shape memory polymers and fibre reinforced shape memory polymers KU Leuven
Shape memory polymers (SMP) can be deformed from a permanent to a temporary shape above their transformation temperature. Upon reheating, the SMP spontaneously returns to the permanent shape. SMP show high deformability, but the recovery stresses are very low, thus limiting the size of the components. This paper presents the first results of an ongoing research to develop large sized components based on SMP. To achieve higher recovery stresses, ...
The Impact of Acceptor-Acceptor Homocoupling on the Optoelectronic Properties and Photovoltaic Performance of PDTSQx(ff) Low Bandgap Polymers Hasselt University
Push-pull-type conjugated polymers applied in organic electronics do not always contain a perfect alternation of donor and acceptor building blocks. Misscouplings can occur, which have a noticeable effect on the device performance. In this work, the influence of homocoupling on the optoelectronic properties and photovoltaic performance of PDTSQx(ff) polymers is investigated, with a specific focus on the quinoxaline acceptor moieties. A ...
