Modern high-efficiency organic light-emitting diodes (OLEDs) based on phosphorescence and thermally activated delayed fluorescence (TADF) rely on host materials that are optimized with respect to many properties simultaneously, including thermal stability, photophysical properties, energy levels, and charge carrier transport. Responding to this challenge, we synthesized and investigated carbazole/dibenzothiophene derivatives as potential hosts, in which carbazole acts as electron donating and dibenzothiophene as electron withdrawing unit. Within this series, the carbazole/dibenzothiophene fraction and the linking phenyl spacer length were systematically varied. Through comprehensive assessment of all material parameters mentioned above and the performance of these host in phosphorescent and TADF OLEDs, we could reliably identify the most suitable molecule for applications and provide guidelines for further material development. With 9-(3?-(dibenzo[b,d]thiophen-4-yl)-[1,1?-biphenyl]-3-yl)-9H-carbazole, bearing one carbazole and one dibenzothiophene unit linked with biphenyl in meta position, we achieved high external quantum efficiency for blue (17.9%) and green (19.4%) modern OLEDs.

Many studies have analyzed the mobility and injection characteristics of charge carriers for organic light-emitting diodes (OLEDs) using hole-only and electron-only devices (HODs and EODs). However, the charge dynamics of a single type of carrier cannot fully represent the characteristics of light-emitting devices such as charge balance, recombination, and efficiency. In this report, we applied the impedance spectroscopy (IS) measurement to operating devices with light-emission. A series of thermally activated delayed fluorescence (TADF) OLEDs with a single or mixed host were fabricated and their electro-optical properties were comprehensively investigated. 4,4?-Bis(N-carbazolyl)-1,1?-biphenyl (CBP) and 2,2?,2″-(1,3,5-Benzinetriyl)-tris(1-phenyl-1-H-benzimidazole) (TPBi) were used for the single host and a mixture of CBP and TPBi (1:1 ratio) was used for the mixed host; 2,4,5,6-Tetra(9H-carbazol-9-yl) isophthalonitrile (4CzIPN) was used as an emitter. In all the OLEDs, the injection and transporting property of holes and electrons were successfully discriminated from the Bode plots of the modulus. Besides, the recombination properties depending on the type of hosts were also thoroughly understood from capacitance (C)-voltage (V), Re(z)-frequency and Cole-Cole plots. The modulus Bode plot revealed that the voltage of the maximum efficiency coincided with the voltage at which the low frequency (electron) signal merges with the high frequency (hole) signal in the mixed host system.

An organic-inorganic hybrid perovskite (OIHP), namely CzEAP, containing a large organic ammonium, 2-(9H-carbazol-9-yl)ethanaminium bromide, was synthesized and exhibited a large band gap of 3.5 eV, a maximum valence band energy level of -6.6 eV, and moderate hole mobility comparable to organic hole-transporting materials. Employing CzEAP as a hole-transporting layer (HTL) in solution-processed organic light-emitting diodes (OLEDs) based on a typical thermally activated delayed fluorescence (TADF) emitter, 2,4,5,6-tetrakis(carbazol-9-yl)-1,3-dicyanobenzene (4CzIPN), resulted in a peak external quantum efficiency of 15.3%, which is nearly two times higher than that of a reference device with a PEDOT:PSS hole injection layer alone. The origin of this significant improvement was found to be the versatile functionality of the CzEAP as the HTL, which is for suppressing exciton quenching, improving the emission efficiency and promoting the reverse intersystem crossing (RISC) rate of TADF emitters via the external heavy-atom effect. This finding unlocks the great potential of OIHPs as excellent HTL materials for high-efficiency solution-processed TADF OLEDs.

Solid-state solvation (SSS) is analogous to liquid-phase solvation but occurs within glassy matrices. Organic solutes with singlet charge transfer (1CT) excited states are especially susceptible to solvatochromism. Their 1CT states and photon emission energies decrease when surrounding molecules with sterically unhindered polar moieties reorient to stabilize them. Thermally activated delayed fluorescence (TADF) organic light-emitting diodes feature such solutes as emitters in the solid state, employing efficient reverse intersystem crossing to harvest the majority of electrogenerated triplets. Here we explore the potential of SSS to manipulate not only these emitters’ 1CT states but also, concurrently, their singlet-triplet energy gaps (I”EST) that control TADF. By solvating the TADF emitter 2PXZ-OXD with progressively increasing concentrations of camphoric anhydride (CA) in a polystyrene film, we find that it is possible to finely tune the emitter’s photophysics. We observe a maximum increase in prompt lifetime and corresponding decrease in delayed lifetime of 60%. By contrast, the photoluminescence quantum yield peaks at an intermediate CA concentration, reflecting competition between increasing reverse intersystem crossing yield and decreasing singlet oscillator strength. Our findings demonstrate technologically relevant fine control of emitter photophysical properties, as varying the extent of SSS reveals the convolved evolution of different kinetic rates as a function of the 1CT state energy and I”EST.
