Spontaneous emission enhancement in planar metal-organic structures (2018)
Journal Article

We provide an experimental investigation of a Purcell enhancement in a silver-organic periodic structure with an organic material CBP (4,4'-Bis(N-carbazolyl)-1,1'-biphenyl). Were fabricated two structures using a thermal evaporation technique with a... Read More about Spontaneous emission enhancement in planar metal-organic structures.

Purcell effect investigation in organic Tamm plasmon structures (2018)
Journal Article

We provide a theoretical and experimental investigation of a Purcell enhancement in a Tamm-plasmon based microcavity structure with an organic (4,4'-Bis(N-carbazolyl)−l,l'- biphenyl (CBP)) active layer. The microcavity structure was fabricated using... Read More about Purcell effect investigation in organic Tamm plasmon structures.

Importance of Chromophore Rigidity on the Efficiency of Blue Thermally Activated Delayed Fluorescence Emitters (2018)
Journal Article

Four new symmetrical donor–acceptor–donor (D–A–D)-type molecules are reported with diphenylamine (DPA) or 10,11-dihydro-5H-dibenz[b,f]azepine (Az) as electron donors and 9,9-dimethylthioxanthene-S,S-dioxide (TXO2) as the electron acceptor. The donors... Read More about Importance of Chromophore Rigidity on the Efficiency of Blue Thermally Activated Delayed Fluorescence Emitters.

Production and Characterization of Vacuum Deposited Organic Light Emitting Diodes (2018)
Journal Article

A method for producing simple and efficient thermally-activated delayed fluorescence organic light-emitting diodes (OLEDs) based on guest-host or exciplex donor-acceptor emitters is presented. With a step-by-step procedure, readers will be able to re... Read More about Production and Characterization of Vacuum Deposited Organic Light Emitting Diodes.

Interfacial TADF Exciplex as a Tool to Localise Excitons, Improve Efficiency and Increase OLED Lifetime (2018)
Journal Article

In this work, we employ a TADF exciplex formed between the emissive layer (EML) host, 26DCzPPy, and the electron transport layer (ETL), PO-T2T at the interface between the EML and the ETL to improve the stability and efficiency of a phosphorescence O...

Thermally Activated Delayed Fluorescence Mediated through the Upper Triplet State Manifold in Non-Charge-Transfer Star-Shaped Triphenylamine–Carbazole Molecules (2018)
Journal Article

Thermally activated delayed fluorescence has been found in a group of tricarbazolylamines that are purely electron-donating, non-charge-transfer (CT) molecules. We show that the reverse intersystem crossing step in these materials is mediated through...

Solution processable small molecule based TADF exciplex OLEDs (2018)
Journal Article

In this work we report the optimisation of the solution processable TADF exciplex emitter in OLED devices formed by the small molecules 9-[2,8]-9-carbazole-[dibenzothiophene-S,S-dioxide]-carbazole (DCz-DBTO2) and 4,4′-cyclohexylidenebis[N,N-bis(4-met...

Chemical and conformational control of the energy gaps involved in the thermally activated delayed fluorescence mechanism (2018)
Journal Article

This review summarises the significant developments in our understanding and control of thermally-activated delayed fluorescence (TADF) molecules and the spin–vibronic coupling mechanism, from which we have designed new generations of emitters. It co... Read More about Chemical and conformational control of the energy gaps involved in the thermally activated delayed fluorescence mechanism.

Triazatruxene: A rigid central donor unit for a D-A3 thermally activated delayed fluorescence material exhibiting sub-microsecond reverse intersystem crossing and unity quantum yield via multiple singlet-triplet state pairs (2018)
Journal Article

By inverting the common structural motif of thermally activated delayed fluorescence materials to a rigid donor core and multiple peripheral acceptors, reverse intersystem crossing (rISC) rates are demonstrated in an organic material that enables uti...

Effects of Ortho-Phenyl Substitution on the rISC Rate of D–A Type TADF Molecules (2018)
Journal Article

Two new donor (D)–acceptor (A) type molecules, PXZ-DBTO2 and PXZ-Ph-DBTO2, configured with phenoxazine donor and dibenzothiophene-S,S-dioxide acceptor are reported. PXZ-Ph-DBTO2, with a phenyl group introduced at the ortho position of PXZ, was used t... Read More about Effects of Ortho-Phenyl Substitution on the rISC Rate of D–A Type TADF Molecules.
