Copper(II) phthalocyanine
Order Code: M341
Copper(II) phthalocyanine is also known as CuPc. It is used widely as an electron donor with fullerene-C60 or phenyl-C61-butyric acid methyl ester (PCBM) in vacuum-deposited organic photovoltaics (OPV). A power conversion efficiency of about 1% has been achieved and an improved efficiency of 4% has been achieved with a pentacene-doped CuPc layer. CuPc is also used as a hole-injection material for light-emitting diodes. It has been found that a thin CuPc layer may effectively enhance the hole injection from the anode to the emissive polymer layer and results in a dramatic decrease of operating voltage of the device.

3-(Biphenyl-4-yl)-5-(4-tert-butylphenyl)-4-phenyl-4H-1,2,4-triazole
Order Code: M601
1,2,4-triazole-based 3-(biphenyl-4-yl)-5-(4-tertbutylphenyl)-4-phenyl-4H-1,2,4-triazole, is also known as TAZ. It is widely used in blue phosphorescent OLEDs (PhOLEDs) to act as an efficient electron-transporting and hole-blocking layer for its high triplet energy level that would confine the triplet excitons within the emissive layer. The low HOMO/LUMO energy level of TAZ is advantageous for blocking holes and facilitating electron injection/transport, thus enhancing the device performance.

4,4′,4′′-Tris[phenyl(m-tolyl)amino]triphenylamine
Order Code: M621
4,4',4''-Tris[phenyl(m-tolyl)amino]triphenylamine is also known as m-MTDATA. It has a very low solid-state ionisation potential, and the quality of its amorphous film has enabled it to act as an effective material for the hole-injection buffer layer (HIL). This facilitates hole injection from the ITO electrode to the hole transporting layer (HTL) and thus potentially lowers the driving voltage of the OLED devices.

Cobalt phthalocyanine
Order Code: M631
Cobalt phthalocynine, also known as CoPc, is a member of metal phthalocyanines (MPcs). They are frequently used in many organic electronic devices such as light-emitting diodes (LEDs), organic photovoltaics (OPVs), organic field-effect transistors (OFETs) and chemical sensors as a p-type semiconducting material. In comparison to other hole-injection layer (HIL) materials, most metal phthalocyanines are water and air stable, thermally stable, and nontoxic. They can be sublimed or sputtered with highly uniform, thin films on a variety of substrates. The MPc chemical structure allows tuning of its ionisation potential or HOMO levels by altering the central atom in Pc macrocycle.

Ir(piq)3
Order Code: M641
Tris(1-phenylisoquinoline)iridium(III) (Ir(piq)3) is a deep red phosphorescent dopant material. There has been considerable attention surrounding quinoline/isoquinoline-based compounds in optoelectronic materials due to their high electron affinities. With greater π-electronic conjugation in an isoquinoline ring, the energy of the lowest unoccupied molecular orbital (LUMO) is significantly lowered, and thus the energy gap is reduced.. The ‘piq’ unit of the ligand part can partially suppress the triplet-triplet annihilation and result in short phosphorescent lifetimes.

TPBi
Order Code: M651
2,2',2"-(1,3,5-Benzinetriyl)-tris(1-phenyl-1-H-benzimidazole) is also known as TPBi. Due to its electron deficiency, it is normally used as electron transport layer material in optoelectronic devices. The low LUMO energy level (2.7 eV) of TPBi also acts as host material for both fluorescent and phosphorescent light emitting systems. It has also been reported that TPBi could be used as electron injection layer material between Alq3 (ETL) and Cs2O3/Al (electrode).
