Накратко на български

Органични молекули, допирани с бор и азот, се разработват като нови полупроводници за електронни устройства. Те могат да заменят силиция, тъй като са по-гъвкави, по-евтини за производство и позволяват по-лесна настройка на своите оптични свойства.

Tailored Materials for Sustainable Technologies: Programming Functional Molecular Components Through Boron-Nitrogen Doping

The primary objective of the STiBNite project was to train 15 early-stage researchers in diverse disciplines including organic chemistry, physical chemistry, materials science, device fabrication, analytical chemistry, and computational chemistry. The goal was to develop novel semiconducting BN-doped molecules and materials. Among the many materials that have shaped our modern lifestyle, doped inorganic silicon (Si) semiconductors stand out as the cornerstone of today’s electronics. However, Si-based devices are often expensive, mechanically brittle, and offer limited chemical tunability. As a result, there is a strong demand for alternative materials that provide improved properties, presenting both timely scientific challenges and economic opportunities. STiBNite addresses this need by targeting the next generation of semiconductor materials: BN-doped macromolecular organics. Although these materials have recently emerged as highly promising candidates, their broader application in devices is hindered by the lack of reproducible and targeted synthetic methodologies. To overcome this, the STiBNite consortium is developing reliable, sustainable, and scalable strategies for synthesizing BN-doped polycyclic aromatic hydrocarbons. These compounds are then rigorously characterized to evaluate their performance. The resulting materials’ optical properties, particularly the energy bandgap and exciton behavior, can be finely adjusted by carefully tuning the molecular structures during synthesis. These optimized materials are subsequently integrated into optoelectronic devices to harness the potential of BN-doped systems as semiconductors fully. These advancements were made possible through the strong collaboration among consortium members and the dedicated work of 15 exceptionally talented early-stage researchers. Trained by leading academic institutions and industry partners, these young scientists have gained deep expertise in organic-based semiconductors. Ultimately, the STiBNite project not only pioneers new materials for future technologies but also cultivates a new generation of scientists, equipped with the skills and experience to thrive in a rapidly evolving and competitive research landscape.

Цел на проекта

The scientific goal of the STiBNite Research Training Network is to develop and apply a bottom-up covalent synthesis and assembly approach to produce advanced organic semiconductors with precisely controllable properties, achieved by perfect positional control of dopant atoms. We plan to produce boron-nitrogen-carbon (BNC) macromolecular materials, either in solution or on surface, starting from programmed polycyclic aromatic hydrocarbons precursors substituted in given positions with BN-doping units (i.e., borazine rings, B3N3). Each will be encoded with a specific BN-doping pattern and concentration to control its optoelectronic and thermal properties. In particular, insertion of borazine rings, which have an insulating, polar character, will disrupt the π-conjugation of the host carbon framework hence tuning its bandgap. These BN-doped PAHs will be developed into either covalent or non-covalent bidimensional materials (2DMs), or transformed into nanoparticles (BNC-NPs), characterized by fully reproducible properties. These innovative engineered BNC macromolecular materials will be thoroughly characterized using several microscopic and spectroscopic techniques, and tested for implementation in lighting and display optoelectronic devices (OPVs, LECs, ECDs) and as thermal management coatings, paving the way for disruptive technological developments in the field. Training is at the core of STiBNite’s plan. We will integrate the traditional training and research schemes of chemistry with modern topical themes and methods imported from engineering and physics. STiBNite’s multidisciplinary training programme of individual projects and interdisciplinary secondments will guide 15 ESRs towards attractive early-stage career opportunities in materials science e.g., as organic, process, and physical chemists, device engineer, etc. This will be made possible by the coordinated effort of a focused and motivated consortium of academics, research centers and EU-based enterprises.
