A new armchair carbon nanobelt synthesized by tuning the regioselectivity of the Scholl reaction of quinquephenyl

A new armchair carbon nanobelt is successfully synthesized by tuning the regioselectivity of the Scholl reaction of 1,1 ':2 ',1 '':4 '',1 ''':2 ''',1 ''''-quinquephenyl. This nanobelt exhibits a preferential binding affinity towards C70 over C60 as found from photoluminescence titration experiments. A new armchair carbon nanobelt is successfully synthesized by tuning the regioselectivity of the Scholl reaction of the quinquephenyl units in the arylated [12]cycloparaphenylene substrate.
