OLED and PLED Materials

There are two main classes of organic light-emitting diodes: OLEDs (small-molecule based light emitting diodes) and PLEDs (polymer light emitting diods). A typical double-heterostructure small-molecule OLED consists of three organic layers sandwiched between electrodes. The organic layers adjacent to cathode and anode are the electron transport layer (ETL) and the hole transport layer (HTL), respectively. Emissive layer (EML) usually consists of light-emitting dyes or dopants dispersed in a suitable host material (often same as HTL or ETL material). This section of the catalog features products suitable for use in each of the OLED layers. Additional Light-Emitting Dopants and Fluorescent Dyes are available in the Photonic and Optical Materials section of the catalog.

PLEDs have relatively simple architectures, with the light-emitting polymer (LEP) layer combining host, emitter and charge transport functions in a single solution-processed layer of the device. We offer a wide selection of LEPs in several major chemical classes proved to be useful for PLED research, including poly(phenylene vinylene) (PPV) and polyfluorene (PFO) polymers. Please refer to Substrates and Electrodes section for a selection of inorganic (Au, ITO, LiF) materials and substrates commonly used in OLED and PLED research.
