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 ...
Development of novel processable electron accepting conjugated polymers containing fluoranthene units in the main chain Hasselt University
Considerable interest exists in the development of novel n-type conjugated polymers, since many currently available polymer systems have insufficient electron mobility and/or electron affinity. In this work, a universal synthesis route is presented towards a new class of n-type conjugated polymers, i.e. poly(p-fluoranthene vinylene) (PFV) and its derivatives. This route is illustrated with three examples, i.e. unsubstituted PFV and ...
Efficient and readily tuneable near-infrared photodetection up to 1500 nm enabled by thiadiazoloquinoxaline-based push–pull type conjugated polymers Hasselt University
The majority of bulk heterojunction near-infrared organic photodetectors (NIR-OPDs) have an absorption window up to 1000 nm (1.2 eV) due to the scarcity of suitable NIR-absorbing electron donor polymers and the challenging energy alignment and/or blend miscibility with electron acceptor materials, strongly complicating to move beyond this wavelength range. Nonetheless, extension of the detectivity further into the NIR is important for ...
Stabilizing cations in the backbones of conjugated polymers Ghent University
Design, Synthesis and Characterization of Functionalized Poly (p-Phenylene Vinylene) Copolymers: The Development of a Universal Method towards Advanced Conjugated Polymers for Device Applications Hasselt University
n Chapter 1, a general introduction to the field of conjugated polymers is given. Conjugated polymers are unique materials, which combine the electronic and optical properties of semiconductors with the mechanical properties and processability of conventional polymers. Generally, organic and polymeric materials have the advantage of being lightweight, flexible, low-cost and straightforward to process. Nowadays, as a result of the wide variety in ...
Influence of the substituent on the chiroptical and magnetic properties of conjugated polymers KU Leuven
In this dissertation, the influence of theside chain on the chiroptical and magnetic properties of conjugated polymers isinvestigated.In the first part regioregularpoly(thiophene)s, substituted with electron rich, conjugated aminostyryl sidechains, are synthesized in order to combine magnetism with conjugated polymers.The formation of magnetic moments (spins), necessary for a materials magneticproperties, is accomplished by selective oxidation ...
Increasing the applicability of conjugated polymers for organic photovoltaics: continuous flow synthesis and elucidation of the importance of structural defects Hasselt University
In the past decade, a tremendous amount of research has been performed in the field of organic photovoltaics, resulting in power conversion efficiencies (PCE’s) of over 10% for single junction polymer-based solar cells. Unfortunately, the photovoltaic performance can differ from batch to batch and it remains rather difficult to synthesize conjugated polymer materials on a large scale and with a high reproducibility in material properties, a ...
Precision synthesis and chiral expression of helical conjugated polymers KU Leuven
The domain of conjugated polymers has already been thoroughly researched. However, up until now the research has mostly been focused on linear polymer structures. This project aims to expand the domain of the conjugated polymers to include different macromolecular structures such as cyclic polymers and helical polymers. These types of materials will show different properties in terms of aggregation compared to the currently existing materials. ...
