Density

1.06 g/ml

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.
