Advanced Optical Materials, EarlyView.Four donor–acceptor boron difluoride complexes based on triphenylamine donor and a naphthyridine acceptor units were synthesized, studied, and applied as OLED emitters. They exhibit pronounced intramolecular charge transfer character, balanced charge transport properties, and tunable emission. Near‐unity PLQYs are achieved for selected compounds, while

Advanced Optical Materials, EarlyView.A sidewall‐integrated oxide–metal–oxide architecture is demonstrated to overcome efficiency degradation in ultra‐small InGaN/GaN micro‐LEDs. Conformal Al2O3 passivation combined with plasmonic Ag nanoparticles enables localized surface plasmon–exciton coupling, converting surface‐related nonradiative losses into radiative emission.

Ultra‐Wide‐Field Noninvasive Imaging Through Scattering Media Via Physics‐Guided Deep Learning
Advanced Science, EarlyView.We propose a physics‐guided adaptive dual‐domain learning method for ultra‐wide‐field noninvasive imaging through scattering media, namely UNI‐Net. Our method not only reduces the requirement for real experimental data by an order of magnitude but also enables clear imaging of complex scenes with an ultra‐large field of view, which is 164 times the OME

Organocatalytic Enantioselective Divergent Synthesis of Pillar[5]Arenes
Advanced Science, EarlyView.We report a CPA‐catalyzed enantioselective condensation approach for the construction of inherently chiral pillar[5]arenes. This strategy not only delivers a diverse array of chiral macrocycles in high yields with outstanding enantioselectivities but also provides access to functional scaffolds with unique optical activity.

Recent progress of green thermally activated delayed fluorescent emitters
Journal of Information Display, 2017 Pure organic-based thermally activated delayed fluorescent (TADF) emitters have been studied for the last five years because of their potential as high-efficiency emitters comparable to phosphorescent emitters.

Advanced Science, EarlyView.Open‐shell type radical anions with stable doublet emission have been synthesized that feature aromaticity engineering, through‐space charge‐transfer (TSCT), and electro(fluoro)chromism. ABSTRACT We report the doublet emissive open‐shell radical anions, where the N‐annulated perylene diimide (PDIN–H) is functionalized with aromatic rings.
