Charge Transfer States in Donor–Acceptor Bulk‐Heterojunctions as Triplet–Triplet Annihilation Sensitizer for Solid‐State Photon Upconversion

Advanced Materials Interfaces, EarlyView.
A near‐infrared photosensitizer that facilitates efficient solid‐state photon upconversion by recycling triplets formed within a fullerene‐based donor–acceptor bulk‐heterojunction system is demonstrated. Spectroscopic investigations reveal that the energy of photogenerated charge transfer states of triplet character (3CT) is subsequently transferred to

TADF‐Emitting Dendrimers for Scalable Bar‐Coating Fabrication of Light‐Emitting Electrochemical Cells

Advanced Materials Technologies, EarlyView.
TADF‐emitting dendrimers promise to enable scalable solution‐based fabrication of efficient electroluminescent devices by the virtue of an attractive set of properties. Here, we report on how light‐emitting electrochemical cells, comprising the TADF‐dendrimer tBuCz2m2pTRZ, can be fabricated by scalable bar‐coating under ambient air and deliver uniform ...

Aggregation‐induced circularly polarized luminescence and delayed fluorescence enabled by activating high‐level reverse intersystem crossing

Aggregate
Circularly polarized luminescence (CPL) materials with delayed fluorescence have attracted much attention due to their ability to efficiently trap triplet state excitons, thereby improving the photoluminescence quantum yields of CPL materials.

Direct Laser Writing of Magnetic Micro Actuators With a Stimulus‐Responsive Compliant Hinge

Advanced Materials Technologies, EarlyView.
This study presents a versatile modular design strategy for adaptive 3D microactuators. Using two‐photon‐induced C,H insertion reactions within solid polymer layers, chemically distinct hinge and stimulus responsive materials are patterned in one step. The hinge's properties enable tunable motion, mechanical control, and reconfigurable actuation across

Reverse Intersystem Crossing and Exciton Harvesting: A Pathway to Low Threshold in Multi‐Resonant TADF Electrically Pumped Organic Semiconductor Lasers

Advanced Optical Materials, EarlyView.
Electrically pumped organic lasing thresholds are lowered by mitigating triplet accumulation through a tailored host‐guest system. Integrating the multi‐resonant TADF emitter DABNA‐2 into a triplet‐scavenging BSBCz host suppresses singlet‐triplet annihilation.

Synthesis and Characterization of Zn-Salophen Complexes with Different D–A Distances: An Approach to Tuning the Intersystem-Crossing Process

Inorganics
A series of novel zinc-salophen (salophen = N, N′-phenylenebis(salicylimine)) complexes (Zn-1–4) with electron donor–acceptor (D–A) structure were synthesized and characterized using a triphenylamine structure as the electron donor. Zn-salophen complexes
