Stable rylene ribbons with record length (dodecarylene) were synthesized Unusual open-shell diradical character was observed from hexarylene onward The observed diradical character was linked to the metallic property of 5-AGNR Infinite polyrylene ribbon is expected to have a small energy gap of 0.21 eV
