    Research Interests and Current projects

    Schiff-base Ligands
    Most of the tritopic ligands used in our group have amine based end caps. Replacing the amine group with alkyl or aryl substituents forming a classical Schiff-base ligand changes the preferred conformation and has profound effects on reactivity and outcome of self assembly reactions.

    Octanuclear Copper Pinwheels
    While the most common outcome of self-assembly reactions for linear tritopic ligands is a [3x3] grid, with copper cations heteroleptic eight copper pinwheel structures are often observed. This outcome is particularly interesting as the copper cations which form the “arms” of the pinwheel have two sites which are occupied by weakly bonded anions or solvent molecules. Replacement of these weakly coordinated entities with strongly bonding, potentially bridging moieties could lead to the linking of the individual clusters to form larger networks, which might display interesting cooperative magnetic effects.

    Functionalization of Tritopic Ligands
    [3x3] grid molecules are approximately square with sides about 2 nm long. Their size, planarity, and especially redox activity makes them good candidates for study from a molecular computing point of view. By adding and electron rich substituent (e.g. Cl, S) to the central pyridine ring we create a situation where on each face of the grid there are three groups, which can bind to a gold surface. STM studies have revealed that grids modified by addition of a sulfide group form an organized monolayer on a flat gold surface. Further electrochemical and surface studies are ongoing.
