Frequently Asked Questions (FAQs)

What are transport layer materials in OLED technology?

Transport layer materials are organic compounds responsible for charge transport within the OLED structure—both for electrons (ETM) and holes (HTM). Proper selection of these materials is essential for device performance, turn-on voltage, and operational stability.

What types of transport layers do we offer?

We offer materials for HTL (Hole Transport Layer) and ETL (Electron Transport Layer), as well as compounds supporting electron injection layers (EIL) and electron blocking layers (EBL). Our portfolio includes a wide range of compounds, from well-established to next-generation structures.

What is the purpose of HTL layers in OLEDs?

The HTL layer is responsible for transporting holes (positive charge carriers) from the anode to the emissive layer. Its role is to ensure high charge mobility, energy level alignment, and to reduce recombination outside the emissive layer (EML).

What is the function of ETL layers?

ETL (Electron Transport Layer) is responsible for efficiently delivering electrons from the cathode to the emissive layer. It must feature a low LUMO level, good thermal stability, and compatibility with adjacent materials.

What technical parameters are crucial when selecting a transport material?

Important parameters include: HOMO/LUMO levels, charge carrier mobility, thermal stability, sublimation temperature, and compatibility with emissive layers and electrode materials. Material choice depends on the architecture of the entire OLED system.

Do transport materials affect the OLED lifetime?

Yes — a proper choice of transport layers helps to optimize charge balance, which leads to reduced overheating, longer device lifetime, and lower operating voltage.

What compounds do we offer in the transport material category?

Noctiluca’s collection includes TTPA, BPPB, B₂PymPm, BPhen, BCP, TPD, TSPO1, and TCNQ—used as HTL, ETL, EIL components and as barrier materials in OLED structures.

Are the offered materials suitable for vacuum sublimation?

Yes, many of our transport materials are available in sublimed grade (≥99.9%), suitable for thin-film deposition in vacuum processes.

Are HTL/ETL materials compatible with commercial emitters?

Yes — our transport layer materials are designed and selected to ensure compatibility with a wide range of commercial and custom OLED emitters, including both TADF and phosphorescent types.

Do we offer support in selecting HTL or ETL materials?

Yes, we provide technical assistance in selecting the appropriate transport material, taking into account energy levels, application requirements, and compatibility with other OLED layers.

What purity levels do we offer for transport materials?

The standard purity of our materials is ≥99.5% (HPLC), and sublimed versions reach ≥99.9%, meeting the requirements of OLED and organic electronics applications.

Is it possible to order a sample for testing?

Of course. We offer transport materials in mg–g quantities, ready for lab testing, prototyping, and initial deployments. On request, test series can also be prepared.

Are Noctiluca transport materials suitable for top-emission OLED structures?

Yes — many of our materials offer high transparency and favorable optical properties, allowing their use in top-emission OLED.

Do we offer custom synthesis of HTL/ETL materials?

Yes, as part of our custom synthesis service, we can design and produce transport materials with specific parameters tailored to defined architectures or customer requirements.

How to order a transport material from our collection?

Just contact us — after confirming technical requirements, we will prepare a delivery offer, quality documentation, and a cooperation proposal. We serve both R&D clients and industrial partners.
