Distinct Ligand‐ and Metal‐Centered Phosphorescence in a Terbium Carbazolyl Complex
Chemistry – A European Journal, EarlyView.Terbium and lanthanum carbazolide complexes show two distinct modes of luminescence: Strongly temperature‐dependent narrow‐line terbium emission could be induced. In addition, both the terbium and the lanthanum complexes show broad‐line interligand emission processes with excited states of microsecond life‐time.

Chemistry – A European Journal, EarlyView.Novel emissive liquid crystalline boron C,N‐chelates were prepared by integrating mesogenic units into the boron C,N‐core. Depending on the substituent at the boron, stable SmA or N mesophases were achieved while maintaining intense blue emission with excellent quantum yields (61%–100%).

Insights into the Photocatalytic Arene Bromination Enabled by Cs2AgBiBr6 Microparticles
Chemistry – A European Journal, EarlyView.A sustainable photocatalytic bromination of electron‐rich arenes is enabled by low‐toxicity Cs2AgBiBr6 double‐perovskite microparticles using HBr as an atom‐economical bromine source. Surface‐derived bromine radicals drive highly selective mono‐bromination under mild conditions.

Synthesis and Characterization of Carbazole‐Containing Aza[7]helicenes
Chemistry – A European Journal, EarlyView.Double ortho fusion led to different aza[7]helicene frameworks showing strong acidochromic behavior, singlet excited energies being more than twice the triplet energy, and high racemization barriers, allowing chiral resolution and ECD measurements. ABSTRACT Azahelicenes have attracted significant interest due to their intrinsic axial chirality and ...

Bifunctional Photocatalysts: Exploiting Proximity for Enhanced Reaction Performance
Chemistry – A European Journal, EarlyView.This review covers the application of the bifunctional approach to photocatalysis as a means to attain (enhanced) enantioselectivity, and, more in general, as a strategy to enhance the catalytic performance through an effective use of short‐lived reaction intermediates.

Exploration, EarlyView.Conjugated microporous polymers (CMPs) have attracted more and more attention as new photocatalysts due to their unique advantages such as high performance, long stability and strong light absorption. This review summarizes the application of CMPs as a photocatalyst in recent years and introduces the catalytic mechanism.

FlexMat, 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 ...
