[16]Cloverphene: a Clover‐Shaped cata‐Condensed Nanographene with Sixteen Fused Benzene Rings

Living in clover: Sequential [4+2] and [2+2+2] aryne cycloadditions allow the isolation of cloverlike and archlike nanographenes (see picture). This approach led to the synthesis of the largest cata-condensed aromatic hydrocarbon that has been obtained to date, a system formed by 16 fused benzene rings (22 benzene rings in total) and 102 sp2 carbon atoms.
