{"title": ["", "High Efficiency Liquid-crystalline Emitters through Multi-resonant Thermally Activated Delayed Fluorescence"], "description": ["", "\nOrientational control of molecular order, anisotropic charge migration, operational lifetime, low cost, high efficiency and colour purity are essential for high-quality organic light emitting diodes (OLEDs). Luminescent discotic liquid crystals (LDLCs) showing columnar (Col) phases (formed by the self-organisation of disc-like, planar, fluorescent molecules decorated with peripheral alkyl chains) are candidate emitters for OLEDs. The increasing acceptance of columnar devices arises from their inherent properties such as anisotropy in conduction, control of molecular order, ease of processability and self-healing of structural defects. However, most LDLCs exhibit broad emission and their internal quantum efficiency is limited to 25% due to their inability to harvest electrogenerated triplets. This means that the external quantum efficiency of EL device has a theoretical maximum of 5-7%. Recently, thermally activated delayed fluorescence (TADF) has become a very attractive approach to emissive materials as they possess a small energy gap between the singlet and triplet excited states. This enables reverse inter-system crossing which in turn leads to the possibility of unit efficiency for emission. One approach to TADF is to use multiple resonance (MR-TADF), which has the advantage that the emission bands are extremely narrow (there are few vibrational effects) leading to very high colour purity. Further, they are realised in planar molecules and so form a perfect template for elaboration into discotic liquid crystals. The self-organisation inherent fluid liquid crystal phases leads to self-healing, high anisotropy of conductivity and exertion of control over the transition dipole moment, all of which will help to maximise the efficiency and performance of an OLED display. As such, this proposal seeks to realise a new paradigm in the design of efficient and effective emitters for OLEDs through the synthesis and characterisation of liquid crystalline MR-TADF materials.\n\n"], "extra_text": ["", "\n\n\n\n"], "status": ["", "Active"]}
