Abstract
Cyclocondensation of α,β-unsaturated aromatic ketones V and VIII with quaternary pyridinium salts VI in the presence of ammonium acetate gave 2,4,6-triarylpyridines I, aryl-substituted diaza-p-terphenyls IIa,b, diaza-p-quaterphenyls IIc,d and diaza-p-quinquephenyls IIe,f. All the new polyphenylene compounds exhibit characteristic luminiscence in the visible spectral region.
