the pyrene moiety, an appealing sumanene derivative 93, namely as pyrenylsumanene, was constructed by the groups of Higashibayashi and Sakurai which display both herringbone and columnarcrystalpacking (Scheme 22) [53]. To synthesize this architecturally interesting molecule, they began with the

emission with high quantum yield (0.82) was observed for pyrenylsumanene in solution, while excimer-type red-shifted emission was evident in the crystalline phase.
