TADF invariant of host polarity
Check out our newest publication in Angewandte Chemie where we demonstrate a really cool behaviour of donor-acceptor Thermally Activated Delayed Fluorescence (TADF) emitters. We also debunk a few misconceptions about TADF that can be clearly explained in the light of our results. You can read our paper here.
Electroluminescence beyond 940 nm
We are pleased to present our new paper in Chemical Science where we demonstrate electro- and photoluminescence beyond 940 nm from thin films of platinum(II) complexes. Check out full article here.
Excimers or aggregates?
We’ve cracked excited states in platinum(II) complexes: stop focusing on excimers and look for aggregates in OLEDs! Plus cool OLEDs with a 1 nm thick light-emitting layer! Check out our new paper here.
Triplet-triplet annihilation in liquid crystals
We have demonstrated triplet-triplet annihilation (TTA) in films of liquid crystal materials. The luminescent liquid crystal gives the best non-doped OLED efficiency reported, thanks to the TTA. Congratulations to Larissa Gomes Franca, the lead author of the work and great thanks to everyone who contributed to this work. You can read this paper here.
Simple synthesis of TADF systems with two different donors
This work is a result of synthetic / photophysics collaboration with the groups of Professor Pierre Audebert and Professor Fabien Miomandre. We congratulate all authors, but especially Dr Antonio Maggiore, the lead author of the work. You can read the paper here.
Themed collection in Frontiers in Chemistry
We are currently accepting submissions to a themed collection Lighting up the Triplet: Advances in Triplet Harvesting in Frontiers in Chemistry. An editorial team lead by Piotr and involving Caroline Murawski, Youhei Takeda and Glib Baryshnikov as the co-guest editors invites contributions in the broad area of topics relevant to triplet harvesting.
Oxygen diffusion in real time
Oxygen from the air is a strong quencher of luminescence. In this example we observe a deoxygenated toluene solution of an orange-phosphorescent platinum(II) complex illuminated with a UV lamp. Observe how slowly oxygen moves through the solution – once air is let into the cell only the very top layer is subject to luminescence quenching. Stirring is necessary in order to observe quenching in the bulk of the solution.
The strength of Homoconjugation
Check out our new paper on the effects of Homoconjugation in Thermally Activated Delayed Fluorescence (TADF) luminophores which has now been published in Journal of Materials Chemistry C. The work was prepared in collaboration with Northumbria University, University of Cambridge and Loughborough University.
Developments in red platinum(II) TADF
We are making a significant progress in developing new platinum-based Thermally Activated Delayed Fluorescence dyes for a future generation of OLEDs. Our recent paper in Journal of Materials Chemistry C emerged from a collaboration between Durham University and Northumbria University and features a novel, improved strategy for platinum-based TADF complexes.
