The mass production of fullerenes and nanotubes faces the problem of their selective production. Here we present special kind of graphene patterns which can be used as initial structures for fullerenes, nanotubes and other carbon nanostructures. We proved in quantum chemical molecular dynamics calculations that these structures transform in a self-organizing way into the desired structures. Our results can initiate new experimental researches for improving the existing carbon nanostructure productions and to develop a new, structure-selective nanolithography of fullerenes, nanotubes and other carbon structures. We present such kind of graphene patterns which generate the self-organizing processes. In our molecular dynamics simulation we obtained the C60 and C70 fullerene, the (5,5) armchair nanotube and (9,0) zigzag nanotube. We present also a graphene pattern for self-organizing Y junction production.
