Formamidinium Iodide (FAI)

Order Code: M551

Formamidinium lead iodide exhibits a narrower bandgap (1.48 eV) than the commonly used methylammonium lead iodide (1.57 eV) meaning it lies closer to that required for optimum solar conversion efficiencies.

CAS number	879643-71-7
Chemical formula	CH₅IN₂
Molecular weight	171.97 g/mol

Formamidinium Bromide (FABr)

Order Code: M561

Formamidinium bromide (FABr), is widely used as a perovskite precursor material for FAPbBr3 or a range of formamidinium lead bromide-iodide mixed halide perovskites (FAPbIyBr3-y). FAPbBr3 material, has an energy bandgap of 2.23 eV, making it an ideal candidate for tandem solar cell applications as well.

CAS number	146958-06-7
Chemical formula	CH₅BrN₂
Molecular weight	124.97 g/mol

Methylammonium bromide (MABr)

Order Code: M571

Methylammonium bromide, also known as MABr, is the precursor of MAPbBr₃ perovskites. Having a bandgap of 2.3 eV (HOMO 5.68 eV, LUMO 3.38 eV), MAPbBr₃ perovskites has been used to modify the bandgap of mixed MAPbX₃.

CAS number	337526-85-9
Chemical formula	C₂₇H₂₃IrN₂O₂
Molecular weight	599.70 g/mol
HOMO/LUMO	HOMO ~ 5.6 eV LUMO ~ 3.0 eV

Ir(piq)2(acac)

Order Code: M671

Bis(1-phenylisoquinoline)(acetylacetonate)iridium(III), also known as Ir(piq)₂(acac), is commonly used as an efficient phosphorescent red emitter as a guest dopant material in PhOLED devices. It has been reported that the piq ligand can partially suppress the triplet-triplet annihilation and exhibit short phosphorescent lifetime.

CAS number	435294-03-4
Chemical formula	C₃₅H₂₇IrN₂O₂
Molecular weight	699.82 g/mol
HOMO/LUMO	HOMO ~ 5.0 eV LUMO ~ 3.0 eV

TCNQ

Order Code: M681

7,7,8,8-tetracyanoquinodimethane, known as TCNQ has a LUMO at 4.5 eV and is most known for the charge transfer salts formed by its radical anion TCNQ in photovoltaics and light-emitting diodes and organic field-effect transistor devices. TCNQ and its derivatives have been used as dopants, leading to an increase in the hole mobility or to the lowering of injection barriers.

CAS number	1518-16-7
Chemical formula	C₁₂H₄N₄
Molecular weight	204.19 g/mol
HOMO/LUMO	LUMO = 4.5 eV

tCP

Order Code: M751

1,3,5-Tris(carbazol-9-yl)benzene is also known as tCP and has three carbazole units attached to the benzene ring meaning it is electron rich and an excellent hole transporting layer (HTL) material. It is mainly used as a phosphorescent host material for light-emitting diodes.

CAS number	148044-07-9
Chemical formula	C₄₂H₂₇N₃
Molecular weight	573.68 g/mol
HOMO/LUMO	HOMO= 5.8 eVLUMO = 2.3 eV

2-TNATA - 4,4′,4′′-Tris[2-naphthyl(phenyl)amino] triphenylamine

Order Code: M611

4,4',4''-Tris[2-naphthyl(phenyl)amino]triphenylamine (2-TNATA) is a starburst type molecule. It gives very homogeneous thin films that are well suited as a hole-injection layer due to the low ionisation potential around 5.1 eV.
