8-Quinolinolato lithium

Order Code: M732

8-Hydroxyquinolinolato-lithium (Liq)


8-Hydroxyquinolinolato lithium, also known as Liq, when coupled with aluminium (Al) is widely used as electron-injection layer (EIL) materials in organic electronic devices. Liq/Al has also been commonly known to be an effective cathode system towards general electron transport layer materials.

CAS number 25387-93-3
Chemical formula C9H6LiNO
Molecular weight 151.09 g/mol
HOMO = 5.58 eV, LUMO = 3.15 eV


Bebq2 - sublimed

Order Code: M741


Bis(10-hydroxybenzo[h]quinolinato)beryllium, also known as Bebq2, is related to Beqq2 in the Beryllium complex family. It is a blue fluorescence emitter with very efficient charge transport ability. The most efficient use of Bebq2 is not as an emitting layer material or a host material (although it is a commonly used host material), but as an electron-transport material.

CAS number 148896-39-3
Chemical formula C26H16BeN2O2
Molecular weight 397.43 g/mol
HOMO = 5.5 eV, LUMO = 2.8 eV


Bepp2 - sublimed

Order Code: M691



Bis[2-(2-hydroxyphenyl)-pyridine] beryllium, also known as Bepp2, is part of the beryllium complex family. It is a blue fluorescence emitter with very efficient charge transport ability. Due to its high electron mobility and high triplet energy level, Bepp2 has been used as electron transporting and hole/exciton blocking layer materials in OLEDs.

CAS number 220694-90-6
Chemical formula C22H16BeN2O2
Molecular weight 349.39 g/mol
HOMO = 5.7 eV, LUMO = 2.6 eV



Order Code: M431


4,4 -bis(2,2 -diphenylvinyl)-1,1-diphenyl, which is abbreviated to DPVBi, is a wide bandgap small-molecule semiconducting material that is widely used as a blue-host emitting material in OLEDs.

CAS number 142289-08-5
Chemical formula C40H30
Molecular weight 510.67 g/mol
HOMO = 5.9 eV, LUMO = 2.8 eV



Order Code: M421


Bis(8-hydroxy-2-methylquinoline)-(4-phenylphenoxy)aluminum, which is also known as BAlq or BAlq3, is commonly used as a blue-emitting layer material in OLEDs. Additionally, it is also used as a hole-blocking layer or as a “barrier-softening” interfacial layer in between the electron-transporting and emissive layers.

CAS number 146162-54-1
Chemical formula C32H25AlN2O3
Molecular weight 512.53 g/mol
HOMO = 5.9 eV, LUMO = 2.9 eV



Order Code: M801


Bis(2-(3,5-dimethylphenyl)quinoline-C,N)(acetylacetonato)iridium(III), known as Ir(dmpq)2(acac), is a highly efficient red phosphorescent emitter that is employed as a dopant material in OLEDs. Ir(dmpq)2(acac) has a higher quantum efficiency when compared with Ir(phq)2acac, and it is believed that the methylation of the quinoline ring of the phq ligand is the major reason for this.

CAS number 1056874-46-4
Chemical formula C39H35IrN2O2
Molecular weight 755.94 g/mol 
HOMO = 5.31 eV, LUMO = 3.26 eV



Order Code: M791


1,4,5,8,9,11-Hexaazatriphenylenehexacarbonitrile, which is abbreviated to HATCN, is one of the members of the 1,4,5,8,9,12-hexaazatriphenylene (HAT) family, which have a electron-deficient, rigid, planar, aromatic discotic systems with excellent π–π stacking ability. As a result, HAT-CN has applications in OLEDs, as either the hole-injection layer (HIL) or charge generation layer (CGL) material.

CAS number 105598-27-4
Chemical formula C18N12
Molecular weight 384.27 g/mol
HOMO 7.5 eV, LUMO 4.4 eV



Order Code: M811

TAPC1,1-Bis[(di-4-tolylamino)phenyl]cyclohexane, also known as TAPC, has been commonly used as a hole transport material in OLEDs due to its high hole mobility. TAPC has a higher ET (2.87 eV) than typical blue phosphorescent guest materials, therefore it can be used as both hole transport layer material and as host for blue phosphorescent such as FIrpic guest molecules. This results in reducing the number of organic layers and leads to simplified OLED structures.
