4,4′-{9,9′-Spirobi[10H-acridine]-10,10′-diyl}dibenzoic acid (L, C29H26N2O4) was designed and synthesized as a new donor–acceptor motif molecule. Due to the large dihedral angle between the planes of the carboxyphenyl group and the spiroacridine moiety, L possess thermally activated delayed fluorescence (TADF).

X-ray detection, which plays an important role in medical and industrial fields, usually relies on inorganic scintillators to convert X-rays to visible photons; although several high-quantum-yield fluorescent molecules have been tested as scintillators, they are generally less efficient.

AbstractIn most instances, thermally activated delayed fluorescence (TADF) emitters are incorporated into a suitable host matrix at low doping concentration in order to reduce emission quenching and to improve organic light‐emitting diode (OLED) efficiency. Here, a combination of molecular dynamics simulations and density functional theory calculations

Organic light-emitting diodes (OLEDs) still face a significant challenge in finding blue thermally activated delayed fluorescence (TADF) emitters that can achieve narrowband emission and high efficiency. In this work, we successfully design and synthesize a novel kind of TADF emitters based on rigid sulfur/oxygen-bridged triarylboron acceptor for ...

AbstractThermally activated delayed fuorescent (TADF) polymers are very suitable for fabricating highly efficient solution‐processed organic light emitting diodes (OLEDs). TADF homopolymers with simple structures are much preferred for preparation, but due to the triplet–triplet annnihilation, most TADF homopolymeric OLED exhibits lower external ...

Thermally Activated Delayed Fluorescence (TADF) in Transition Metal Complexes
Thermally activated delayed fluorescence (TADF) is a temperature-dependent luminescence mechanism that allows the harvesting of both singlet and triplet excitons for fluorescence emission. Consequently, TADF-active compounds exhibit excellent photophysical properties, such as high luminescence efficiencies and long excited-state lifetimes.Mareen Stahlberger +2 more

AbstractCurrent research on thermally activated fluorescence (TADF) emitters is mainly based on the molecular levels, while the aggregation states of TADF emitters are to be explored deeply. Now two multifunctional emitters are reported with simultaneous TADF, aggregation induced emission (AIE), and multicolor mechanochromic luminescence (MCL) features.
