Photochemical Decatungstate‐Catalyzed Hydroacylation of Maleimides

open access: yesEuropean Journal of Organic Chemistry, EarlyView.
A photocatalytic protocol to access substituted succinimides via tetra‐n‐butylammonium decatungstate photocatalysis is reported. This direct radical‐driven hydroacylation of a variety of N‐substituted maleimides shows tolerance to various aldehydes (or alkanes), affording differentially substituted succinimides in high yields. Succinimides constitute a

Large employers and apprenticeship training in Britain [PDF]

open access: yes
We consider two aspects of the link between apprenticeship and large employers in Britain: the contributions of apprenticeship to employers supplies of intermediate skills and of employers to the Advanced Apprenticeship programme.

Divergent Synthesis of Polycyclic Derivatives via Gold Catalysis

open access: yesEuropean Journal of Organic Chemistry, EarlyView.
Gold(I)‐catalyzed cycloisomerization enables the formation of complex 3D structures from simple enyne precursors. This study presents a divergent strategy to synthesize functionalized bicyclic and tricyclic scaffolds from a common alkynyl ketone.

Photoinduced Solution‐Stable Radicals via Intramolecular Charge Separation From anti‐Kasha Emissive BN‐Azepines

open access: yesElectron, EarlyView.
A series of BN‐azepines with a twisted heptagonal B–N donor–acceptor framework was synthesized, enabling stable photoinduced radicals in solution. Upon photoexcitation, charge separation between the triarylamine donor and boron acceptor yields a longer‐lived triplet state, which can generate a nitrogen radical cation through electron transfer.

A Closed‐Loop Human Resource Management Framework for Energy Efficiency: Integrating Predictive Optimization With Behavioral Implementation

open access: yesEnergy Science &Engineering, EarlyView.
The proposed framework operates as a continuous cycle: organizational data streams feed into predictive optimization, which generates energy efficiency targets. These targets are translated into behavioral directives through human resource management mechanisms.

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 ...
