Project: New Organometallic Materials with Thermally Activated Delayed Fluorescence for Applications in High Efficiency OLEDs

Acronym: TADFOLED
Main Objective: The main objective of this proposal is the synthesis of new low-cost luminescent boron and copper(I) organometallic
complexes exhibiting TADF and their application as emissive layers in the fabrication of highly efficient OLEDs.
In the light of the team's excellent previous results on the boron compounds and recent preliminary results on
iminopyrrolyl copper(I) complexes, the main guidelines for this proposal are: A) improving the emissivity and stability
of the boron complexes, preferably emitting in the blue; B) Preparation of new iminopyrrolyl Cu(I) complexes of
neutral bidentate (P,N), (P,S) and (P,O) ligands, towards the development of highly emissive TADF-exhibiting materials; C) Preparation of new mixed iminopyrrolyl boron-Cu(I) metal complexes bridged through organometallic
linkers, towards the development of red and white light emitters. The syntheses of the new complexes will be developed according to synthetic organometallic methodologies
referenced in the literature for these metals and ligands, which will be fully characterised (molecular and photophysical
wise), enabling the assessment of the potential application of these compounds in electroluminescent (EL) devices.
TD and TD-DFT calculations will be used to ascertain the origin of luminescence exhibited by the metal complexes
and to rationalise the observed photophysical properties.
LED structures of the type ITO/active layer/metal cathode will be fabricated in order to evaluate the EL properties of
these metal complexes.
