Sky-blue Solution-processed TADF and Hyperfluorescent OLEDs via a High-Work-Function PEDOT:PSS:PFI Hole Injection Layer

arXiv:2607.18474v1 Announce Type: new
Abstract: Solution-processed OLEDs offer a scalable route to large-area devices, but achieving competitive efficiency in multilayer stacks remains a challenge due to difficulties in hole injection as well as solvent orthogonality between layers. A hole injection layer (HIL) based on a blend of PEDOT:PSS and a perfluorinated ionomer (PFI) addresses both challenges simultaneously: surface segregation of PFI during film drying creates a high-work-function interface improving hole injection into high-ionisation potential host materials, while the insolubility of the blend in aromatic solvents prevents intermixing with subsequently deposited layers. Using this HIL with a solution-processed mCPCN:SpiroAC-TRZ emissive layer, sky-blue OLEDs with a peak external quantum efficiency (EQEmax) of 21.7%, an external quantum efficiency (EQE) of 20.2% at 100 cd m-2, a peak luminance of 29,000 cd m-2 and a full width at half maximum (FWHM) emission linewidth of 69 nm are demonstrated. The PFI-based HIL approach is extended to the photochemically stable TADF emitter 5TCzBN (EQEmax 18.4%, FWHM 73 nm) and to sensitized / hyperfluorescent OLEDs incorporating the multi-resonance TADF terminal emitters n-DABNA (EQEmax 22.8%, FWHM 26 nm) and the dendrimer TCzBN-BMes (EQEmax 20.4%, FWHM 29 nm). These results establish the PEDOT:PSS:PFI HIL as a broadly compatible platform for high-performance solution-processed TADF OLEDs.

A couple of pics from a little bike packing trip around Dorset over the weekend. We took the train to Upwey (just outside Weymouth) and cycled 110km off road across Ridges, Bridle Paths and old Roman Roads back to Poole

I told Elliot to stop when we drove near this pond in Hooksett (Dubes Pond) because I'd had recurrent dreams that I was driving a talented girl to get trained by a witch on ashop by its shore

Our “premium meth” is starting to burn.
“It’s going to blow!” Hoyt shouts as smoke clouds the kitchenette.
Sweating in a hazmat suit, I switch off the burner. The goo bubbling in our saucepan is supposed to be blue. Blue Sky.
The boss won’t like that it now resembles tar.
It’s nearly midnight, and we’re eight hours into an elaborate game that almost no one wins.

#SilentSunday #LandscapePhotography
We expected rain (but no ⚡⛈️).
So we got our jackets, did our errands with our little bike trailer - and were lucky because it didn't even rain 💪
✅ Saved fuel again
✅ Physical activity
✅ Faster way to detach from work
✅ Saw a couple of cats
Totally recommended!

Apparently it’s National Lighthouse Day, which we learned at the bottom of the Currituck Beach Lighthouse. May serendipity always conceal our ignorance.
The lighthouse’s 1 million bricks are being repointed, but you could still climb the 220 steps of this 151 year old tower.

Looking East from the Ute Trail. November 2013.
I spent last week catching some of the last snow of the season (probably) in the Bogong High Plains. A mix of hiking, snowshoeing, skiing and trail running. Brilliant weather made up for the lack of snow, and it’s always beautiful up there one way or another. #bushwalking #straya
I promise I won’t annoy you with any more posts about the album/collection after this, but I just had to thank Mastodon people who came to the ‘Otherscapes’ listening party yesterday. It made all the work put into it feel better. That anyone would come is encouraging, but especially that some stayed for 5, 6, 7 hours into the 11 hour release. (And to see comments come in when I woke up again a few hours later was a fun indicator of my suboptimal hours of sleep in generall. 😆)

Afterwards I was quite surprised about the distance and height that I covered. But it was worth it.

I've always loved this funny little yellow house, hidden in a courtyard at the University of Edinburgh's School of Geography. You can see Portobello and the sea to the left of the building. Wonderful 18th century original case and sash windows (they slide up and down using rope, a counterweight and a pulley!)

What a morning and long day it was last week! Was already out & about for 3 hours when I got to this place, earlier mostly taking hundreds of images of the nearby (~500m away) Breslauer Hut and vicinity during sunrise... The first large (and loud) group of people already got up at 4AM, getting ready for climbing Wildspitze, another group left an hour later, as did I. Maintenance/repair works on the hut continued at 08:30, taking lots more pictures to document, interviewin…
My #FootpathFriday contribution... I wish I was there today to be honest..
This was part of a bike and hike where we returned in the rain. But as we were prepared for it, it was more fun than expected!

My wife and me both have commitments during the day. So we just did a 2h cycling to our beautiful reservoir and back. It went really well and it felt good to be on the bike.
