- Synthesis of oligo(diazaphenyls). Tailor-made fluorescent heteroaromatics and pathways to nanostructures
-
Oligoaza derivatives of biphenyl, terphenyl, quaterphenyl, quinquephenyl, sexiphenyl, septiphenyl, octiphenyl, noviphenyl, deciphenyl and dodeciphenyl and poly(pyrimidinylenephenylene) can be synthesized from readily accessible vinamidinium salts and amidines or N,N,N'- tris(trimethylsilyl)amidines. The fluorescence of these systems can be tuned over a wide spectral range by varying number and positions of N atoms. Oligo(diazaphenyls) are thermally and photochemically stable, are easier to reduce than oligopheny]s, can be dissolved at any rate in strong acids and show strong blue fluorescence in solution as well as in the solid state.
