Research lines

Our group is mainly focusing on material synthesis, with a particular emphasis on structural purity and profound material characterization, and possesses all synthesis and characterization facilities to be competitive on an international level. Moreover, the integration in the Institute for Materials Research (imo-imomec) provides access to state-of-the-art device fabrication and (optoelectronic) characterization tools. All projects are conducted in close collaboration with Materials Physics colleagues to unravel the processes underlying device performance.

Fluorescentie 2

(Near-Infrared) Emission - OLEDs

In recent years, a number of organic semiconducting materials have been developed to exploit the light emission principle of thermally activated delayed fluorescence (TADF). This concept enables the realization of unique optical and electronic properties arising from the efficient thermal equilibration of the lowest singlet (S1) and triplet (T1) excited states of organic fluorophores. As a result, TADF-based organic light-emitting diodes (OLEDs) show significantly upgraded device performances, comparable to those provided by traditional rare metal complexes. To realize efficient TADF, organic luminophores require a very small energy difference (ΔEST) between their S1 and T1 excited states, which enhances the T1->S1 reverse intersystem crossing rate. Such excited state equilibration is attainable by intramolecular charge transfer within systems containing spatially separated donor and acceptor moieties.

In the DSOS group, advanced TADF materials are designed, synthesized, and characterized by a rational approach combining complementary computational and synthetic materials expertise. We are particularly interested to extend the TADF emission range to the near-infrared (NIR). In parallel, we also explore similar materials for triplet-triplet annihilation (TTA).

OPV Triangle 2020

Organic Photovoltaics (OPVs)

Over the past 12 years, the DSOS group has been active in the field of organic/polymer solar cells. These organic thin-film photovoltaics have demonstrated strong potential as an innovative source of renewable energy, adding appealing features to classical solar cell technology, in particular in terms of architectural freedom (flexibility, reduced weight, color, semitransparency), low-light performance, and low-cost (high-throughput) large-area production.

Despite the impressive progress in the field over the last years, especially in terms of device efficiency (nowadays exceeding 18%), further dedicated research efforts are still required to enable successful market entrance. In this respect, the DSOS group addresses all three parts of the 'photovoltaic triangle', i.e. efficiency, stability, and cost, with dedicated (Ph.D.) research projects, pursuing the rationalization of structure-property relations. Nowadays, we mainly focus on truly transparent OPVs, indoor OPVs, and the implementation of continuous flow chemistry to improve material and device reproducibility, in strong collaboration with the OOE group (Prof. K. Vandewal) at imo-imomec.

Opd device

Organic Photodetectors (OPDs)

For UV-visible light detection, organic photodetectors already match and even surpass the performance of state-of-the-art inorganic photodetectors. Unfortunately, organic materials generally show limited absorption in the near-infrared (NIR) part of the spectrum. For this reason, we target novel NIR-absorbing materials for regular bulk heterojunction NIR-OPDs as well as organic cavity enhanced photodetectors, with the aim to elucidate the intrinsic limitations of NIR photodetection based on organic semiconductors (in the pursuit of a marketable technology).

We have recently shown that the main factor limiting the specific detectivity is non-radiative recombination, which is also known to be the main contributor to open-circuit voltage losses in OPVs. Based on this finding we concluded that OPDs have the potential to be a useful technology up to 2 μm, given that high external quantum efficiencies can be maintained at these low photon energies. To further elaborate on the fundamentals defining these limitations, we now focus on the influence of specific material imperfections on the material properties and device performance, in close collaboration with the OOE group (Prof. K. Vandewal) at imo-imomec.

BCI

Organic Electrochemical Transistors (OECTs)

Recently, the DSOS group has broadened its research activities towards organic electrochemical transistors. These devices consist of a semiconducting polymer channel, capable of conducting ions as well as electronic charges. This interesting characteristic gives OECTs the ability to connect the soft and ionic world of biology with the hard and electronic world of solid-state semiconductor physics. Even though the field is still in its infancy, it is believed that OECTs will revolutionize electronic healthcare through applications in biosensors, electrophysiology, brain-computer interfaces (BCI’s), etc. To achieve mixed conduction, hydrophilic analogs of established semiconducting polymers are synthesized by incorporating various hydrophilic side chains on the polymer backbone.

In the EU-funded MITICS project, we focus on the bioelectronic applications of OECTs (notably brain-computer interfaces), while the FWO WEAVE project (in collaboration with the Vandewal and Banerji groups) deals with the more fundamental understanding of electronic-ionic interactions for high-performance and stable OECTs.

Theranostics

Over the years, the DSOS group has broadened its scope of activities to organic semiconducting materials for advanced healthcare, for which we strongly collaborate with the NSI (Nanobiophysics and Soft matter Interfaces) group at imo-imomec. From an initial focus on (luminescent) conjugated polymer nanoparticles for bioimaging, we recently moved on to push-pull (BODIPY) dyes for image-guided photodynamic therapy. The aim is to cover the whole research chain from computational materials design to (NIR-photoactive) photosensitizer synthesis and characterization, incorporation of the advanced photosensitizer in specifically designed nanoparticles, to studies of the cytotoxicity and intracellular dynamics of the nanoparticles in cells and biological tissues using advanced optical imaging techniques.

Porph Cold

Porphyrinoid Materials

The DSOS group has a long-standing interest in the synthesis and applications of porphyrinoid materials (push-pull porphyrins, corroles, …) and related BODIPY (boron dipyrromethene) dyes, specifically in relation to organic electronics and advanced healthcare applications. Detailed photophysical characterization of these oligopyrrolic chromophores is conducted in close collaboration with spectroscopists and theoretical chemists.
