The coordination of 2-pyridyltetrazolate and ortho -xylene-linked bis(NHC)cyclophane to Pt( ii ) yielded a novel complex characterised by enhanced pure deep-blue emission, whose intensity can be modulated via methylation of the tetrazole ring. Coordination of 2-pyridyltetrazolate and ortho -xylene-linked bis(NHC)cyclophane to Pt( ii ) yields bright deep-blue phosphorescent complexes, whose emission intensity can be modulated via reaction with methyl triflate.
