    Based on space integration using a flow microreactor system, the title unsymmetrically substituted pyracenes with an extremely long C-C bond [1.714(2)1.739(4) Å] are readily accessible, whose structures demonstrate nonadditive substituent effects on expanding the polyarylated C 1C 2 bond in crystal. The bond lengths rather exhibit correlation with the eclipsing degree of the C sp 3C sp 3 bond, which is more affected by the intermolecular factors such as crystal packing.
