Titanyl phthalocyanine
Order Code: M702

Titanyl phthalocyanine, known as TiOPc, is a family member of highly photosensitive phthalocyanine compounds. It is one of the most successful materials used in the photocopying industry. TiOPc is used as a water photooxidation agent and is built into sensors for NO2 detection. It has also been made into devices for organic light-emitting diodes (OLEDs) and organic photovoltaics (OPVs) with photon to current efficiency of over 4% reported by using TiOPc as the light-harvesting dye and C60 as the electron acceptor.

CAS number | 26201-32-1 |
Chemical formula | C32H16N8OTi |
Molecular weight | 576.39 g/mol |
HOMO/LUMO | HOMO = 5.7 eV, LUMO = 3.9 eV |
N,N′-Bis(3-methylphenyl)-N,N′-diphenylbenzidine
Order Code: M401

N,N′-Bis(3-methylphenyl)-N,N′-diphenylbenzidine, also known as TPD, is commonly used in organic electronic devices as hole transport materials. Additionally, TPD is used as a blue-violet light emitting material or host material on the phosphorescence organic light emitting diodes due to its wide energy band being 3.2 eV with highest occupied molecular orbital (HOMO) and lowest unoccupied molecular orbital (LUMO) 5.5 eV and 2.3 eV respectively.

CAS number | 65181-78-4 |
Chemical formula | C38H32N2 |
Molecular weight | 516.67 g/mol |
HOMO/LUMO | HOMO = 5.5 eV, LUMO = 2.3 eV |
Tris(4-carbazoyl-9-ylphenyl)amine
Order Code: M472

Tris(4-carbazoyl-9-ylphenyl)amine, also known as TCTA, has three carbazole units as the pendants and triarylamine at the core, which means it is electron rich and thus is widely used as a hole-transport and hole-injection material in light-emitting diodes and perovskite solar cells. With low electron mobility, TCTA has also been used as exciton/electron blocking layer materials because of its high lying LUMO energy level (LUMO = 2.4 eV).

CAS number | 139092-78-7 |
Chemical formula | C54H36N4 |
Molecular weight | 740.89 g/mol |
HOMO/LUMO | HOMO = 5.83 eV, LUMO = 2.43 eV |
FIrpic (F2IrPic)
Order Code: M711

Bis[2-(4,6-difluorophenyl)pyridinato-C2,N](picolinato)iridium is abbreviated to FIrPic. F2IrPic or Ir(difppy)2(pic), is one of the most commonly investigated bis-cyclometallated iridium complexes, particularly in the context of organic light emitting diodes (OLEDs). This is because its attractive sky-blue emission, high emission efficiency, and suitable energy levels as a phosphorescent dopant material.

Chemical formula | C28H16F4IrN3O2 |
Molecular weight | 694.66 g/mol |
HOMO/LUMO | HOMO = 5.8 eV, LUMO = 3.1 eV |
Ir(ppz)3
Order Code: M721

Tris(phenylpyrazole)iridium, also known as Ir(ppz)3, features a small lowest unoccupied molecular orbital (LUMO) of approximately 1.6 eV. It has been commonly used in organic light emitting diodes and other organic electronic devices, such as organic photovoltaics, as an electron-blocking layer (EBL). It has also been reported that Ir(ppz)3 doping can enhance low wavelength optical absorption capacity and doping a small amount of Ir(ppz)3 can also improve the crystallinity of P3HT.

Chemical formula | C27H21IrN6 |
Molecular weight | 621.71 g/mol |
HOMO/LUMO | HOMO = 5.0 eV, LUMO = 1.6 eV |
OXD-7 - sublimed
Order Code: M451

1,3-bis[2-(4-tert-butylphenyl)-1,3,4-oxadiazo-5-yl]benzene, abbreviated to OXD-7, is a widely used electron transporting material due to its good electron withdrawing properties from the oxadiazole units. In conjunction with poly(9-vinylcarbazole) (PVK) which is electron donating, OXD-7 is the most commonly used hybrid type host due to its good solubility and film morphology from the bulky tert-butyl units.
