Bond and Antibond Resonances: A Unified Framework for Singlet Biradical Character

open access: yesChemistry – A European Journal, EarlyView.
The electronic structure of a variety of singlet biradicaloids may be described in the Lewis picture using single antibonds as the central bonding motif. In conjunction with a consistent set of biradical indicators, we can resolve some long‐standing disputes over the biradical character of molecules such as O3 and S2N2.

Phosphorescent Iridium Hydrazinonicotinic Acid (HYNIC) Complexes That Bind to Prostate Specific Membrane Antigen: Potential Photodynamic Therapy of Prostate Cancer

open access: yesChemistry – A European Journal, EarlyView.
A phosphorescent iridium(III) complex has been prepared with a 6‐hydrazinonicotinic acid (HYNIC) ligand tethered to a lysine‐ureido‐glutamatic acid pharmacophore, which binds to an enzyme, called prostate‐specific membrane antigen (PSMA), which is overexpressed in prostate cancer.

Carbon Dots: An Emerging Frontier for Green and Sustainable Civil Engineering Materials

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Traditional civil engineering materials (CE materials) are usually involved with high‐energy consumption during manufacturing, significant maintenance costs, and substantial environmental impacts throughout their life cycles. The progress of nanotechnology is catalyzing a green and sustainable transformation within the field.

Thermally activated delayed fluorescence exciplex sensitizers with fast reverse intersystem crossing for improving efficiency stability of organic light‐emitting diodes based on multi‐resonance emitters

open access: yesFlexMat, EarlyView.
Two exciplex emitters are constructed based on a host‐guest doping strategy, and their exciton dynamics processes are investigated in depth. High‐performance OLEDs are fabricated by employing these exciplexes as emitters or sensitizers, providing excellent electroluminescence efficiencies and low efficiency roll‐offs.

Flexible white thermally activated delayed fluorescence polymer with alkyl spacer and side‐chain encapsulation for efficient solution‐processed white organic light‐emitting diodes

open access: yesFlexMat, EarlyView.
A “gemstone‐necklace” FASCE strategy synthesizes single‐component white polymers (PTF‐Qx) by alternating rigid TADF units with flexible alkyl chains. The non‐doped rigid device achieves a high EQE of 15.66% with stable white emission (CIE: 0.36, 0.46).

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 ...

Flexible organic room‐temperature phosphorescent materials

open access: yesFlexMat, EarlyView.
This review highlights recent advances in flexible organic room‐temperature phosphorescent (RTP) materials, covering both organic crystal and polymer systems. It discusses strategies to overcome the inherent rigidity and enhance the mechanical flexibility of organic RTP materials, aiming to enable their practical applications in anti‐counterfeiting ...
