Functionalized supramolecular nanoporous arrays for surface templating.

[摘要]：Controlled self-assembly and chem. tailoring of bimol. networks on surfaces is demonstrated using structural derivs. of 3,4:9,10-perylenetetracarboxylic diimide (PTCDI) combined with melamine (1,3,5-triazine-2,4,6-triamine). Two functionalized PTCDI derivs. were synthesized, Br2-PTCDI and di(propylthio)-PTCDI, through attachment of chem. side groups to the perylene core. Self-assembled structures formed by these mols. on a Ag-Si(111)? ??R30?surface were studied with a room-temp. scanning tunneling microscope under ultrahigh vacuum conditions. The introduction of side groups can have a significant effect upon both the structures formed, notably in the case of di(propylthio)-PTCDI which forms a previously unreported unimol. hexagonal arrangement, and their entrapment behavior. These results demonstrate a new route of functionalization for network pores, opening up the possibility of designing nanostructured surface structures with chem. selectivity and applications in nanostructure templating.
