Polytriarylamines are a class of air-stable organic semiconductors, which are a result of the low-lying HOMO energy limiting air oxidation. Long-term operation of these materials is further validated by their inertness to fluctuations in current due to changes in humidity, with charge mobilities of up to 5×10-3 cm2/Vs being observed.
Their excellent solubility in organic solvents, beyond the conventional chlorinated aromatics, means that they can be easily processed into devices. Average molecular weights can be tuned for specific applications, and we encourage requests for specific ranges.

Pseudouridine is one of the most abundant modified nucleosides found throughout RNA. It is a structural analogue of uridine, whereby the C1-N1 bond in uridine is replaced with a C-C bond in pseudouridine, giving rise to additional rotational freedom and flexibility, whilst increasing the hydrogen-bond capability at N1.
