pubmed-article:19940243pubmed:abstractTextDespite a large steric bulk of C(60), a molecular graphene with a covalently linked C(60) pendant [hexabenzocoronene (HBC)-C(60); 1] self-assembles into a coaxial nanotube whose wall consists of a graphite-like pi-stacked HBC array, whereas the nanotube surface is fully covered by a molecular layer of clustering C(60). Because of this explicit coaxial configuration, the nanotube exhibits an ambipolar character in the field-effect transistor output [hole mobility (micro(h)) = 9.7 x 10(-7) cm(2) V(-1) s(-1); electron mobility (micro(e)) = 1.1 x 10(-5) cm(2) V(-1) s(-1)] and displays a photovoltaic response upon light illumination. Successful coassembly of 1 and an HBC derivative without C(60) (2) allows for tailoring the p/n heterojunction in the nanotube, so that its ambipolar carrier transport property can be optimized for enhancing the open-circuit voltage in the photovoltaic output. As evaluated by an electrodeless method called flash-photolysis time-resolved microwave conductivity technique, the intratubular hole mobility (2.0 cm(2) V(-1) s(-1)) of a coassembled nanotube containing 10 mol % of HBC-C(60) (1) is as large as the intersheet mobility in graphite. The homotropic nanotube of 2 blended with a soluble C(60) derivative [(6,6)-phenyl C(61) butyric acid methyl ester] displayed a photovoltaic response with a much different composition dependency, where the largest open-circuit voltage attained was obviously lower than that realized by the coassembly of 1 and 2.lld:pubmed
