Custom Synthesis

Noctiluca’s Team have over 15 years of experience in both research and development projects, as well as in the production of organic and organometallic compounds from milligrams to multi-kilograms.

Our experience includes among others, high purity organometallic compounds of gallium, zirconium, tin, and indium ALD and CVD applications; Gratzel type dyes for DSSC applications; and other organic materials.

We have the necessary laboratory equipment for the synthesis of organic and organometallic compounds sensitive to air and moisture, reactors with a capacity of up to 50 L, industrial rotary evaporator, microreactors, and flow reactors, electrochemical reactors, etc. We have GC and GCMS, HPLC and HPLC MS, IR and UV-VIS spectrometers as well as NMR (700 MHz, 400 MHz, and 300 MHz), ICP-MS, SEM and TEM.

Transport layer materials

Efficient transport of holes and electrons to the emissive layer that is important for the performance of the device. Thermal and electrochemical stability, as well as mobility properties drive the performance of the OLED.

1.1. Hole Transport Layer (HTL)
HTL materials are mainly aromatic amines with high hole mobility properties like: F4TCNQ, CBP, NPB, mCP, TAPC, TCTA, mTDATA, TPD, TCP, 2-TNATA, BCBP, DPAVBi, TTPA and Tris-PCz, CzSi.

1.2. Electron Transport Layer (ETL)
Electron deficient materials are used as ETL materials: TPBi, TmPyPB, PPT, B4PymPm, DPPS, B3PymPm, DPEPO, B2PymPm, B3PyPB, BTB, T2T and TSBF.

Injection layers

On top of that, Noctiluca offers emitters in the whole colour palette, ranging from yellow, through green to blue, with red in heavy R&D process – we are a one-stop-shop for IJP OLEDs.

2.1. Hole Injection Layer (HIL)
HIL materials improve the injection of holes from the anode into HTL by reducing the energy barrier between these layers. Most common HIL materials are: 2-TNATA, F4TCNQ, NPB, TCTA, mTDATA and TPD.

2.2. Electron Injection Layer (EIL)
Electron deficient materials are used as ETL materials: TPBi, TmPyPB, PPT, B4PymPm, DPPS, B3PymPm, DPEPO, BEIL materials reduce the energy barrier between the cathode and the ETL. One of the most frequently used EIL material is TPBi.

Blocking Layers

Excitons are confined within the emission layer by using respective HBL and EBL materials which greatly increase the performance of the OLED devices.

3.1. Hole Blocking Layer (HBL)
These materials prevent from exciton leakage from the emission layer to the ETL. Most popular HBL materials are: DPEPO, B3PyPB, BTB, TPBi, TmPyPB, B4PymPm, DPPS, B3PymPm and B2PymPm.

3.2. Electron Blocking Layer (EBL)
These materials prevent exciton leakage from the emission layer to the HTL. Most popular EBL materials are: TTPA and NPB.

Host materials

Dispersion of a dopant in a host is common for all four generations of OLED devices, especially for phosphorescent, TADF and Hyperfluorescent technologies. The choice of the right host is crucial for the performance of the device. A new approach is to apply a bipolar host which consists of donor and acceptor groups in a molecule – such structure of the host has a great influence on the stability and lifetime of the devices. Among the most frequently applied hosts are:

CBP, T2T, mCP, TmPyPB, TAPC, TCTA, TPD, ADN, TCP, CzSi, mCBP, DPEPO, CDBP, TSBF, BCBP, BCPO (bipolar), mCPSOB (bipolar), BCzPh, PYD-2Cz (bipolar), 26DCzPPy (bipolar), 35DCzPPy (bipolar), Cab-Ph-TRZ (bipolar), PPT (bipolar).
