Helical Systems for Chiral Organic Light Emitting Diodes Project combines the expertise on the chirality domain of different research groups located all along Europe.

The principal research goal of HEL4CHIROLED is the preparation of chiral Organic Light-Emitting Diodes (OLEDs) and Organic Light-Emissive Transistors (OLETs) based on new small helical molecules, helical π-conjugated oligomers and helical lanthanide complexes.

For this, the HEL4CHIROLED project is mainly focused in three axes:

1-. The discovery and development of new chiral molecules and materials.

The OLEDs and OLETs devices will be based on new small helical molecules, helical π-conjugated oligomers and polymers, and new helical lanthanide complexes.

2-. Exploring a new approach to increase the EQE of conventional OLEDs and the charge transport in transistors by:

– Using the emission of circularly polarized light (CPL) to improve the performance of displays based OLEDs, and to allow additional functionality stereoscopic displays.

– Manipulating the spin of electrons by using a chiral molecule, to improve spin effects (Chiral Induced Spin Selectivity, CISS).

3-. To apply this knowledge in the preparation of chiral OLEDs, chiral OLETs and chiral Organic Photovoltaics (OPVs).

Such knowledge will provide a paradigm shift in OLED technologies, developing new materials sets and approaches.
