Forcing a priori tetracoordinate atoms into planar configuration represents a promising concept for enhanced reactivity of p-block element-based systems. Herein, the synthesis, characterization, and reactivity of calix[4]pyrrolato gallates, constituting square...

The Pictet-Spengler reaction was applied to synthesize benzobispyrrolo[3,2-c]quinolines as new scaffolds for organic electronics. The adressed compounds are nitrogen-enriched analogues of -extended indolocarbazoles formally accessed by the isosteric replacement of...
