2D Supramolecular Structures of a Shape-Persistent Macrocycle and Co-deposition with Fullerene on HOPG
TLDR
Two 2D supramolecular structures of macrocycle 1 and 1/C60 obtained on HOPG by self-assembly under ambient conditions and investigated by high-resolution STM show that the donor-acceptor interaction between C60 and the electron-rich units of the ring is the dominant factor for the structure formation.Abstract:
Two 2D supramolecular structures of macrocycle 1 and 1/C60 have been obtained on HOPG by self-assembly under ambient conditions and investigated by high-resolution STM. The monolayers of 1 are characterized by structures with perfect ordering over relatively large areas. In the case of 1/C60, the size of the macrocycle 1 and the presence of two individual bithiophene units per ring lead in the final superstructure to a 1:2 stoichiometry. The fullerenes are not trapped at the graphite surface inside the macrocyclic holes but are located around the periphery of the bithiophene units. This clearly shows that the donor−acceptor interaction between C60 and the electron-rich units of the ring is the dominant factor for the structure formation.read more

Controlling molecular deposition and layer structure with supramolecular surface assemblies
TL;DR: This work uses hydrogen bonding to guide the assembly of two types of molecules into a two-dimensional open honeycomb network that then controls and templates new surface phases formed by subsequently deposited fullerene molecules, and finds that the open network acts as aTwo-dimensional array of large pores of sufficient capacity to accommodate several large guest molecules.
