Structurally Tunable Self-Assembled 2D Cocrystals of C60 and Porphyrins on the Ag (110) Surface

摘要: Due to the donor–acceptor nature of their supramolecular interactions, nanostructured porphyrin-fullerene self-assembled architectures show attractive properties that can be exploited in high efficiency solar cells. In this work, we six different ordered bicomponent (C60) networks are obtained by controlling peripheral functionalization meso-tetraphenylporphyrins (TPP) with amino groups and stoichiometry aggregates C60 on Ag (110). Such grouped two general classes, depending structural habit: so-called “stripes” phases, formed alternating monomolecular stripes TPP, “pores” where a fullerene net accommodates isolated TPP molecules nanometer-sized pores. These phases interest field surface-supported electron systems, since they represents rare example fullerene-containing ...
