Highly efficient and stable blue organic light-emitting diodes (OLEDs) cannot be easily obtained simultaneously. In particular, the efficiency roll-off as a reference index to evaluate lifetime of deep-blue OLED at high luminescence is still severe. A novel molecule (CzSiTrz) connected with carbazole triazine fragments by nonconjugated silicon atom designed. An intramolecular charge transfer emission intermolecular exciplex in aggregated state are obtained, resulting dual-channel...
Thermally-activated delayed fluorescence (TADF) emitters—just like phosphorescent ones—can in principle allow for 100% internal quantum efficiency of organic light-emitting diodes (OLEDs), because the initially formed electron-hole pairs non-emissive triplet state can be efficiently converted into emissive singlets by reverse intersystem crossing. However, as compared to emitter complexes with their bulky—often close spherical—molecular structures, TADF emitters offer advantage align them...
The role of band bending on the efficiency charge transfer across TiO2(110) single crystal surface has been measured in ultrahigh vacuum, absence a wide range site inhomogeneities, impurities and solvent effects, particle size effects. adsorption Cl2 (electron acceptor) molecule O2 have found to enhance hole transport from TiO2 18O2 molecules adsorbed oxygen vacancy sites, increasing rate electron stimulated desorption (ESD) 18O2. This confirms that O2-ESD is mediated. Conversely, CH3OH,...
Abstract Organic thermally activated delayed fluorescent (TADF) materials can harvest 100% of the electrically generated excitons as a result their small singlet–triplet energy difference. However, maximizing external quantum efficiency (EQE) device also requires enhancing light out‐coupling efficiency. This work presents new acceptor–donor–acceptor (ADA) emitter employing an indolocarbazole donor and diphenyltriazine acceptors that show nearly‐completely horizontal orientation regardless...
White organic light-emitting diodes (WOLEDs) possess excellent electro-optic conversion efficiency for state-of-the-art light sources and play an important role in energy consumption carbon emission reduction. Because of the multiple cells or emitters, structure normal WOLEDs is sophisticated, resulting high fabrication costs low long-term stability. To overcome these hurdles, based on platinum (Pt) complexes with a single layer demonstrate promising potential. Herein, we report regulation...
Structure–property relationship of pyridine-modified δ-carboline derivatives as bipolar hosts for highly efficient blue OLED.
This work reported an unpresented rare-earth-ion bearing metal–organic framework (MOF) Y10(C8H4O4)6(CO3)3(OH)12 built of inorganic slabs as structural units. Eu3+ has been introduced into the lattice to make it optically active. Systematical analysis combined with single crystal X-ray diffraction demonstrates was incorporated endowing MOF promising optical activity. Even though there a trace amount < 1%, this compound displayed excellent luminescent activity quantum efficiency reaching up...
TADF copper(<sc>i</sc>) complexes were made by co-depositing carboline derivatives and copper iodide. δ-Carboline derivative-based OLEDs showed 6 times higher efficiency than α-carboline ones.
Abstract Thermally activated delayed fluorescence (TADF) molecules are regarded as promising materials for realizing high‐performance organic light‐emitting diodes (OLEDs). The connecting groups between donor (D) and acceptor (A) units in D–A type TADF could affect the charge transfer luminescence performance of aggregated states. In this work, we design synthesize four using planar twisted linkers to connect aza‐azulene triazine (A). Compared with linkers, ones ( Az‐NP‐T Az‐NN‐T ) can...

Conjugation-extended carbazolophane donors, dicarbazolophanes (DCzp), were designed and synthesized using a multifold stepwise Pd-catalyzed Buchwald–Hartwig amination/ring cyclization process. Furthermore, elaboration of the DCzp core is possible with introduction pendant carbazole derivative groups. This provides way to tune optoelectronic properties thermally activated delayed fluorescence (TADF) compounds DCzpTRZtBu, dtBuCzDCzpTRZtBu, dMeOCzDCzpTRZtBu. Solution-processed organic...
