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.

This is not the 669 area code and nothing on this map of the San Francisco region of California is accurate.
The shape of California isn’t even right.

One of the nice things about not having ads or any kind of revenue from my site is that I no longer get the diamond-pressure bum-hole puckering feeling I used to get when I had a hosting company and a site would go down. I don’t even have monitoring set up and it’s freeing.
But go kick an LLM in the dick for stealing so much of my shit that you can’t read it except in some inaccessible pay-for-wrongness shitty chat venue.

a major performing arts center on Saadiyat Island set to open by 2030.
Designed by the late architect Frank Gehry,
it will seat over 6,000 patrons across a main 2,000-seat multipurpose hall,
a 3,500-seat amphitheater,

Of course SF needs to give the Mayor more power to do what he wants. Look at the stream of evidence about the high standards for transparency and honesty /s
Please, vote NO on D, E & F - Consolidating power in the executive DOES NOT "Clean up CIty Hall" - it enables poor practices.

No one, it seems, knows why cyberattackers would target Suisun City,
a sleepy, marsh-front suburb of 29,000 people on the northeast outskirts of the San Francisco Bay Area.
But target it, they did,
with crippling effects.
Whoever they are.
