文摘

Mixed (difluoro)phenylpyridine/(difluoro)phenylpyrazole tris-cyclometalated iridium complexes were prepared in order to study theeffect of fluorination and the pyridine/pyrazole ratio on the emissionand electrochemical properties. Increasing fluorination and replacement of pyridine by pyrazole both leads to a widening of theHOMO-LUMO gap and generally leads to a blue shift in emission.
