Description
Packaging
1, 5,10 g in glass bottle
Application
High-mobility material used for white OLEDs to increase hole injection and transport. It is the best solid-state hole transporting material, to date, used to replace the liquid electrolyte for DSSC solar cells, due to an excellent pore-filling property in nanoporous TiO2 film with pore size of around 30-50 nm; attributed to its small molecular size.
Re:Sublimation is a technique used to obtain ultra pure-grade chemicals. For more details about sublimation, please refer to the Sublimed Materials for OLED devices .

Usage
Usage of Spiro-OMeTAD from Inorganic caesium lead iodide perovskite solar cells,Giles E. Eperona, Giuseppe M. Paternòbc, Rebecca J. Suttona, Andrea Zampettibc, Amir Abbas Haghighirada, Franco Caciallibc and Henry J. Snaitha* :
Subsequently substrates were transferred to nitrogen atmosphere and from this point, during fabrication
and testing, devices were never exposed to ambient air. Perovskite precursor was deposited as described
above. The hole-transporting layer was then deposited via spin-coating a solution of 86.9mg/ml of 2,2',7,7'-
tetrakis-(N,N-di-p-methoxyphenylamine)9,9'-spirobifluorene (spiro-OMeTAD) in chlorobenzene, with
additives of 9.7mg/ml Spiro(TFSI)2 prepared in-house following a published procedure,1 and 10μl/ml 4-tertbutylpyridine.
Spin-coating was carried out in a nitrogen-filled glovebox at 2000rpm. Gold electrodes were
then thermally evaporated under a vacuum of ~10-6 Torr, at a rate of ~0.1nm/s, to complete the devices.

[3]: Doped with the below concentrations
50 mM spiro-OMeTAD in chlorobenzene
Co( III )-complex (FK209) first dissolved into an acetonitrile stock solution prepared with concentrations in the range 4 to 33 mM before being added to the Spiro/chlorobenzene solution
FK209 stock solution mixed with Spiro/chlorobenzene solution to give overall 7.7 mol% FK209 to Spiro-OMeTAD
Also doped with a stock solution of Li-bis(trifluoromethanesulfonyl)imide (Li-TFSI) at 170 mg and TBP at 46.6% by volume in acetonitrile
Spin-coated at 3000 rpm for 30s
