Results in brief

Helical systems for chiral organic light emitting diodes

Chirality is the property of left-handed and right-handed objects in the 3D space. In Nature, chirality is known to play a major role in biological systems such as in proteins and polysaccharides. In chemistry and materials science, chiral molecular and supramolecular architectures may also provide added value, related to their inherent 3D structure and their chirality-related electronic and optical properties. The principal research goal of HEL4CHIROLED is the preparation of chiral Organic Light-Emitting Diodes (OLEDs) and other related opto-electronic devices based on new small helical molecules, helical π-conjugated oligomers and helical lanthanide complexes. In this project, we explore new approaches to increase the performances of opto-electronic devices: – Using the emission of circularly polarized light (CPL) to improve the performance of displays based OLEDs, and to allow additional functionalities in stereoscopic displays. – Manipulating the spin of electrons by using a chiral molecule, to improve spin effects (Chiral Induced Spin Selectivity, CISS). For these purposes, a great diversity of helical molecules, covalent and supramolecular polymers, together with chiral lanthanide complexes need to be prepared, thoroughly studied, and implemented into devices.

Project objective

In the HEL4CHIROLED project, coordinated by a woman, the principal research goal is the preparation of chiral Organic Light-Emitting Diodes (OLEDs) and Organic Light-Emissive Transistors (OLETs) based on new small helical molecules (HEL-PI), helical pi-conjugated oligomers (HEL-OLIGO) and helical lanthanide complexes (HEL-Ln). Such knowledge will provide a paradigm shift in OLED technologies, developing new material sets and approaches that take advantage of i) the Chiral Induced Spin Selectivity (CISS) effect for improved performance in OLEDs and ii) the emission of circularly polarized light (CPL) to improve the performance of displays based on OLEDs, and to allow for additional functionality stereoscopic displays, enhanced bandwidth optical communication, etc). Efficient circularly polarized (CP) emissive OLEDs and OLETs and Spin Selective devices (Spin-OLEDs and Spin-OLETs) are targeted. The input of private sector beneficiaries and partners is critical to the scientific objectives, as well as to the enhanced training environment. Work packages combine involvement from both academic and private sectors that will feed into the overall goal through secondments, regular virtual meetings and face-to-face network meetings. The symbiosis of the developments that will take place in HEL4CHIROLED will create a research and training environment that is world-leading and optimally tailored to capitalise, for example, on the investment that has been made on chirality-related technologies. The ESRs will be trained in world-leading laboratories and/or in private beneficiaries and will benefit from the exchange of best practice among beneficiaries and partners, and from unique training events. HEL4CHIROLED will therefore ensure that European research remains competitive in the global market, and that the trained researchers will be uniquely well-placed to contribute to the development of novel optoelectronic devices, displays and imaging technology of the future.
