Abstract Various phenacenes possessing chrysene, picene, and fulminene frameworks were prepared by using a continuous-flow synthetic protocol in which Wittigreaction affording diarylethenes and their Mallory photocyclization producing phenacene skeletons were sequentially performed. The Wittigreaction solution, containing the diarylethene obtained from an arylaldehyde and an arylmethyltriphenylphosphonium

the synthesis of six precursor molecules for the rational synthesis of isomerically pure armchair, zigzag, or chiral single-walled carbonnanotubes (SWCNTs). The polycyclic aromatic hydrocarbons possess the required carbon connectivity for the generation of extended hemisphericalbuckybowls with predefined geometry through intramolecular cyclodehydrogenation. The precursors for the shortcarbon nanotubes
