Low‐Coordination Solvation Engineering Enables Efficient and Stable Perovskite Solar Cells

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
This work introduces a kind of low‐coordination solvent, dimethyl carbonate (DMC), to replace a part of DMSO and DMF. DMC substitutes a part of DMSO to coordinate with PbI2 to change the chemical environment of PbI2. What is more, DMC promotes the formation of the nucleation of α‐FAPbI3 crystals.

Push–Pull Ynamines and Push–Pull Ynamides: Synthesis, Structure, Reactivity, and Application

open access: yesEuropean Journal of Organic Chemistry, EarlyView.
Push–pull ynamines and push–pull ynamides, which carry an EWG and an amino or amido group as EDG, are highly interesting classes of EDG‐EWG alkynes that have been intensively studied due to their exceptional reactivity. In this review, the synthesis, structure, reactivity, and application of push–pull ynamines, push–pull ynecarbamates, push–pull ...

Visible‐Light‐Promoted, (Photo)catalyst‐Free Synthesis of 3‐Sulfonyl‐Azaspiro[4.5]trienones via Arylazo Sulfones

open access: yesEuropean Journal of Organic Chemistry, EarlyView.
A set of 3‐sulfonyl‐azaspiro[4.5]trienones have been obtained via a metal‐ and photocatalyst‐free visible‐light‐driven dearomative strategy. The protocol exploits arylazo sulfones, which act simultaneously as the light absorber and sulfonyl‐radical source, enabling ipso‐spirocyclization of differently substituted N‐aryl propiolamides.

Spirobifluorene fusion in multiple resonance frameworks enables efficient pure‐red OLEDs with narrowband emission and suppressed efficiency roll‐off

open access: yesFlexMat, EarlyView.
An orthogonal spirobifluorene‐fusion strategy is introduced for B/N/O‐alternated MR frameworks, enabling improved kRISC (5.46 × 103 s−1), high ΦPL (97%), and narrow‐band pure‐red emission. Vacuum‐evaporated OLEDs incorporating this emitter achieve an EQEmax >40% (FWHM = 36 nm) and exhibit exceptionally low efficiency roll‐off at high luminance ...

Fluorene‐based blue emitters: On the path to electrically pumped organic lasers

open access: yesFlexMat, EarlyView.
Electrically pumped efficient operation remains unrealized, a major challenge in optoelectronics. Fluorene‐based blue‐emitting semiconductors are promising gain media, thanks to their structural tunability and favorable emission properties. This review summarizes recent advances, highlights their reliability and versatility in lasing, and outlines key ...

Prognostic Impact of Tumor Stage and Growth Pattern in Sinonasal Adenoid Cystic Carcinoma: A 15‐Year Population‐Based Study

open access: yesHead &Neck, EarlyView.
ABSTRACT Background Sinonasal adenoid cystic carcinoma (AdCC) has a limited prognosis. This study assesses its incidence and prognostic factors in The Netherlands, focusing on histopathological features. Methods Adult patients diagnosed during 2008–2022 were retrieved through the Netherlands Cancer Registry and the Dutch Pathology Registry.
