Synthesis and Self‐Assembly of a Rigid Exotopic Bisphenanthroline Macrocycle: Surface Patterning and a Supramolecular Nanobasket

Abstract: The synthesis and characterisation of a rigid nanoscale macrocycle with two exotopic phenanthroline binding sites is reported. Scanning tunnelling microscopy (STM) at the solid-liquid interface reveals the formation of highly ordered monolayers of macrocycles with dimensions that are in good agreement with the calculated structure. Using the HETPHEN concept several bisheteroleptic coordination complexes with other phenanthrolines and a nanoscale basket assembly were prepared in presence of copper(I) ions. NMR … Show more

“…Following the work of Schmittel and colleagues (52,53), we reasoned that the bulky ligands of 1a might favor exchange with those of a less hindered copper(I) complex to give a mixed-ligand species as the thermodynamic product. Indeed, this substitution occurred; the aqueous reaction of the two homoleptic complexes 1a and 3 (43) resulted in ligand exchange, giving heteroleptic complex 4 (Eq.…”

“…Tetrahedral metal ions have been combined with substituted bis-and tris-phenantholine-based ligands to produce oligonuclear grids [62], boxes [63], and baskets [64] as shown in an example of a box-like structure (Fig. 14) [63].…”

“…Porous molecular monolayers are used as two-dimensional hosts for molecular guests, which may be employed for molecular selection or the isolation of single molecules. They have been obtained from macrocycles at the interface between an organic solution and the basal plane of graphite, providing pores in the range of 1.2 to 2.7 nm [19][20][21][22][23]. Alternatively, supramolecular two-dimensional structures have been self-assembled at such solid-liquid interfaces, which are stabilized van der Waals interactions between pending alkyl chains [11,[24][25][26][27][28].…”
