RT Conference Proceedings T1 Merging Theoretical Spectroscopy & Computational Chemistry: Thermally Activated Delayed Fluorescence (TADF) as a new light-emitting mechanism for OLEDs A1 Sancho-García, Juan C. K1 Espectroscopia K1 Química computacional AB We present recent advances and investigations related with a new mechanism for lightemission in conjugated molecules, Thermally Activated Delayed Fluorescence (TADF), seeking to harvest both the singlet and triplet excitons generated under electrical excitation ideally achieveing a 100% of efficiency. The new strategy may fuel the use and manufacturing of 3rd generation OLEDs, although a complete understanding of the molecular mechanism is not fully uncovered yet. Therefore, we will review our recent efforts to address some challenging issues using quantum and atomistic models [1-6]. Among them, we will remark how the mixed nature of the excited-states involved (chargetransfer or locally-excited) ultimately control the singlet-triplet energy difference, and how this is a dynamic process mediated by conformational fluctuations and spin-orbit coupling YR 2019 FD 2019-02-11 LK https://hdl.handle.net/10630/17287 UL https://hdl.handle.net/10630/17287 LA eng NO Campus de Excelencia Internacional Andalucía TECH DS RIUMA.
