Abstract

Four novel blue/green luminescent compounds, Zn (2-py-in) 2 (THF)(1), BPh2 (2-py-in)(2), Be (2-py-in) 2 (3), and BPh2 (2-py-aza)(4), where 2-py-in= 2-(2-pyridyl) indole and 2-py- aza= 2-(2-pyridyl)-7-azaindole, have been synthesized and fully characterized. The 2-py-in ligand and 2-py-aza ligand in the new compounds are chelated to the central atom. Compounds 2-4 are air stable and readily sublimable, with a melting point above 250° C. ...
