Carbon nanotubes (CNT) and fullerenes form van-der Waals crystals. Unlike covalent or ionic crystals where the relations between structure and properties are well understood the structures and physical properties of self-assembled structures based on vdW interactions are sensitive to the thermal energy, the preence of templating moieties and surfaces. Molecularly engineered supra-structures comprising  CNTs  scaffolds decorated by fullerene molecules and fullerene assemblies are an example of a hybrid supra -structure that may combine the electronic and mechanical properties of CNTs with the optical and excellent electron acceptor characteristic of the fullerenes. In this project we design and characterize a library of supra-structures comprising scaffolds of non-functionalized, individual CNTs and fullerenes assemblies. We expect that the geometry and dipole moment of CNT will affect the self-organization of the fullerene molecules at the CNT surface, via a mixture of dispersion forces, and  dipolar interactions leading to the formation of new types of hybrids with electrical and optical properties that depend on the nano-structure, and the intermolecular interactions.
