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.

Macrocyclic metal chelators have been utilised throughout the biochemical industry for numerous years. These specific examples act as reactive intermediates which can be labelled with targeting vectors prior to deprotection and complexation with an appropriate metal centre. Typically, metals such as gadolinium, copper or zinc have been used to generate targeted MRI contrast agents, radiopharmaceuticals or phosphate anion receptors, respectively.
We have expanded our expertise to become more involved at the interface of chemistry and biology, serving industries working in biotechnology, diagnostics and medicine.
