Thermally activated delayed fluorescence (TADF) polymers are designed and synthesized by grafting the TADF emitter to side chain of polycarbazole backbone. By employing these with large ratio component high photoluminescence quantum yield as emitters, solution-processed light-emitting diodes achieve a maximal external efficiency 16.1% at luminance around 100 cd m-2 .
A single polymer with TADF feature has been developed by the side-chain engineering strategy. Employing these copolymers as emitting layers results in a high exciton utilization efficiency of 63.7%.
Multi-carbazole encapsulation is demonstrated as a simple strategy for the development of solution-processed TADF emitters. The resulting OLED achieves high external quantum efficiency 12.2% non-doped fluorescent OLEDs.
Benzothiadiazole-based D–A–D structured red TADF emitter results in high-performance OLEDs with a maximum EQE of 8.8% and CIE (0.61, 0.39).
The exploitation of blue polymer emitters is great importance for the application solution-processed organic light-emitting diodes (OLEDs) in full color display. highly efficient thermally activated delayed fluorescence (TADF) polymers are rarely reported up to now. Herein, we report an approach construct TADF by ring-opening metathesis polymerization (ROMP) norbornene. By side-chain engineering strategy, endowed with distinct features. use these polymeric emitters, nondoped OLEDs achieved a...
Road geometric information and a digital model based on light detection ranging (LiDAR) can perform accurate inventories three-dimensional (3D) descriptions for as-built roads infrastructures. However, unorganized point clouds complex road scenarios would reduce the accuracy of extraction modeling.

Current mainstream spectroscopic scintillators for the detection of high-energy radiation are based on inorganic crystals and ceramics, which difficult to scale up. Efforts have been made synthesize plastic nanocomposite scintillators, though resulting light yield is rather low, leading low photopeak intensity poor energy resolution.

An adamantane-based host material, namely, 4-{3-[4-(9H-carbazol-9-yl)phenyl]adamantan-1-yl}benzonitrile (CzCN-Ad), was prepared by linking an electron-donating carbazole unit and electron-accepting benzonitrile moiety through adamantane bridge.
