Summary: To achieve efficient red emitters, a novel asymmetric red thermally activated delayed fluorescence (TADF) emitter, TPA-AQ-DCP, was developed. By incorporating a host group into the emitter with an asymmetrical structure, electron and hole transport within the emitter was improved, reducing concentration quenching. As a result, TPA-AQ-DCP exhibited a high photoluminescent quantum yield (PLQY) of 79.2% and a fast radiative rate constant (kr) of 6.60×107 s-1, leading to better electroluminescent (EL) performance. TPA-AQ-DCP-based devices achieved efficient external quantum efficiency (EQE) of 11.76-17.60% with an emission peak of 610-620 nm for doping ratios ranging from 5 wt% to 25 wt%.

Summary: A new small organic NIR-II fluorophore molecule (ZS-1010) based on intermolecular charge transfer was developed as a NIR-II fluorescent probe for trimethylamine (TMA) detection, which is crucial for the diagnosis of cardiovascular disease, chronic kidney disease, and diabetes. ZS-1010 demonstrates strong absorption and emission in the NIR-II region due to its push-pull electron system. When interacting with TMA, the fluorescence of ZS-1010 is quenched, making it the first example of a TMA fluorescent probe in the NIR-II window with deep penetration, fast response speed, high selectivity, and pH stability.

Summary: Genetically encoded probes with red-shifted absorption and fluorescence are ideal for imaging applications, but red and far-red fluorescent proteins have very low quantum yields. Understanding the mechanisms of nonradiative relaxation in red fluorescent proteins can help develop proteins with higher quantum yields. By evaluating local electric fields experienced by the chromophore in the protein environment, it was found that the twisted intramolecular charge transfer mechanism plays a dominant role in most studied RFPs, providing important guidelines for shifting the absorption wavelength to the red while maintaining high brightness.

Summary: This work presents a novel hot exciton fluorescent material based on benzo[c][1,2,5]thiadiazole and chiral binaphthol, which enables circularly polarized luminescence (CPL) through a chiral perturbation strategy. The molecule displays both CPL and hybridized local and charge transfer (HLCT) properties concurrently. Circularly polarized organic light-emitting diodes (CP-OLEDs) utilizing this material as the emitter achieve high external quantum efficiency (EQE) and moderate circularly polarized electroluminescence (CPEL) dissymmetry factor. Furthermore, sensitivity to a thermally activated delayed fluorescence material significantly improves the efficiency of HLCT fluorescent CP-OLEDs.

Summary: A low molecular weight (277 g/mol) donor-acceptor conjugate (sensor 1) with intramolecular charge transfer (ICT) characteristics was synthesized. Sensor 1 exhibited weak ICT fluorescence in solution but strong emission in the solid state due to C-H···O hydrogen bonds that inhibit free rotation of the exocyclic C-C single bond. Sensor 1 showed red fluorescence in the solid state and its colorimetric and fluorometric responses to cyanide were due to the nucleophilic addition of cyanide to the β-conjugated carbon of the indanedione group, inhibiting ICT. Portable paper-based test kits based on sensor 1 allowed fast and quantitative naked-eye cyanide detection.

Summary: One of the most important challenges in organic light-emitting diodes (OLEDs) is the development of highly efficient blue-emissive materials. In this study, a series of blue-emissive materials with donor-pi-acceptor (D-pi-A) structures containing a fluorene pi-bridge were synthesized and investigated. It was found that the insertion of the fluorene pi-bridge not only promoted the formation of hybrid local and charge-transfer excited states with high photoluminescent quantum yield (PLQY), but also enhanced hole mobilities through intermolecular face-to-face stacking. As a result, the non-doped OLED using TPACFOXZ achieved a high maximum external quantum efficiency of nearly 10% with balanced hole and electron mobilities.

Summary: The influence of molecular design on the performance of organic light-emitting diodes (OLEDs) was studied by designing four blue-emissive compounds. Phenyl group insertion enhanced conjugation and regulated the locally excited component, leading to high photoluminescent quantum yield and maintained charge transfer property. On the other hand, a large group substitution hindered aggregation and resulted in poor carrier mobilities. By utilizing these design strategies, non-doped OLEDs with balanced carrier mobilities, high external quantum efficiency, and low efficiency rolling-off were realized.
