The organic light-emitting diode (OLED) represents a high-performance optoelectronic apparatus composed of organic layers for charge transport and emission. When a voltage is applied, the OLED’s dual carrier injection mechanism introduces both electrons and holes into the electroluminescent material situated between two electrodes. This interplay generates its distinctive electroluminescent light of specific color and device capabilities, determined by the organic components integrated into the device.

OLEDs are mainly categorized into two classes: those based on small molecules and those based on polymers (PLEDs). In a typical small-molecule OLED with a double-heterostructure, three organic layers are positioned between electrodes. The layers adjacent to the cathode and anode function as the electron transport layer (ETL) and hole transport layer (HTL), respectively. The emissive layer (EML) usually incorporates light-emitting dyes or dopants dispersed within a suitable host material, which is often the HTL or ETL substance. In contrast, PLEDs exhibit a simpler architecture where the light-emitting polymer (LEP) layer combines host, emitter, and charge transport roles within a single solution-processed layer of the device.

Our offerings encompass a range of cutting-edge OLED materials characterized by high purity. This collection includes sublimed small molecule light emitters and dopants, light-emitting polymers, host materials emitting phosphorescent and fluorescent light, electron transport (or hole blocking) materials of both inorganic and sublimed organic nature, hole injection and hole transport materials, thermally activated delayed fluorescent (TADF) dopants, and photosensitizing materials.

Furthermore, we provide an array of inorganic materials (such as Au, ITO, LiF) and substrates. These are commonly employed in the construction of OLED and PLED devices, serving as essential elements for substrates and electrodes. Our innovative LEPs cover significant chemical classes, including prominent polymers like poly(phenylene vinylene) (PPV) and polyfluorene (PFO).
