Dendri-LEC Family: Establishing the Bright Future for Dendrimer Emitters in Traditional and Graphene-Based Light-Emitting Electrochemical Cells

In this research paper, STiBNite ESRs 9 and 13 present the implementation of dendrimers as emitters in light-emitting electrochemical cells (LECs), which offers low-cost synthesis, easy upscaling, and comparable stabilities to state-of-the-art emitters. The molecular design focuses on exchanging peripheral substituents to tune photophysical and electrochemical features, leading to enhanced stability and ion conductivity, and excellent compatibility with biogenic electrolytes, even with graphene-based devices. This work establishes a bright future for dendrimers as sustainable lighting sources.

Dual-Phosphorescent Heteroleptic Silver(I) Complex in Long-Lasting Red Light-Emitting Electrochemical Cells

In this research paper, STiBNite ESR 9 contributes to a thoughtful ligand/complex design strategy towards the first red-emitting Ag(I) complex, [Ag(xantphos)(deebq)]PF₆, featuring (i) outstanding stabilities upon reduction and (ii) thermally equilibrated dual-phosphorescence. This achievement resulted in red light-emitting electrochemical cells with superior stabilities and irradiances compared to the prior art.

ESR 6 Laura: Theoretical Chemistry

In this video, ESR 6 Laura (UCLouvain) describes why Theoretical Chemistry is an important tool in research, both to predict and rationalize properties of future materials.

Laura’s role in STiBNite project is to support and direct, with computational simulations, experimental scientists on the design and synthesis of new molecules, and to predict the properties of not-yet-existing BN-doped materials.

STiBNite: project goals and PhD training

In this short interview, recorded during the STiBNite consortium meeting in Munich (September 2021), STiBNite coordinator Prof. Davide Bonifazi (UNIVIE), explains the goal of the project and the importance of an international experience in the PhD.

The STiBNite project trains 15 PhD students while working towards the development of a new generation of semiconductors, based on renewable organic materials doped with Boron and Nitrogen, for application in electronic devices such as displays, solar cells and transistors.

peri-Acenoacene Ribbons with Zigzag BN-Doped Peripheries

In this research paper, STiBNite ESRs Marco Franceschini and Martina Crosta (UNIVIE) present the synthesis and the properties of a series of BN-doped molecular ribbons.

The BN-graphenoids in this study show systematic red-shift of their UV−vis absorption and emission spectra, as well as a decrease in their oxidation potential, upon elongation of the fused aromatic backbone. In addition, the ribbons’ emission shows a Thermally-Activated Delayed Fluorescence (TADF) component. All these properties are highly desirable features to engineer p-type organic semiconductors.
