Synthesis and characterization of highly fluorescent and thermally stable π-conjugates involving spiro[fluorene-9, 4'-[4H]indeno[l, 2-b]furan]

Abstract

Spiro[fluorene-9, 4'-[4H]indeno[1, 2-b]furan] was synthesized, and its π -conjugation was efficiently elongated using palladium-catalyzed C-H arylation of a furan moiety. The resulting π-conjugated compounds showed intense fluorescence and extremely high thermal stability.
